Last.fm: Социальная музыкальная платформа и веб-радио

Social music Web radio site

Last. fm Limited is a music website founded in the United Kingdom in 2002. Using a music recommender system called "Audioscrobbler", Last. fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to, either from Internet radio stations, or the user's computer or portable music devices. This information is transferred ("scrobbled") to Last. fm's database either via the music player (including, among others, Spotify, Deezer, Tidal, Qobuz, MusicBee, SoundCloud, and Anghami) or via a plug in installed into the user's music player. The data is then displayed on the user's profile page and compiled to create reference pages for individual artists. On 30 May 2007, it was acquired by CBS Corporation via its streaming division CBS Interactive, today a part of Paramount Global, for £140 million (US$280 million, ). The site formerly offered a radio streaming service, which was discontinued on 28 April 2014.

The current Last. fm website was developed from two separate sources, Last. fm and Audioscrobbler, which were merged in 2005. Audioscrobbler began as a computer science project of Richard Jones when he attended the University of Southampton School of Electronics and Computer Science in the United Kingdom, with the term scrobbling defined as the finding, processing, and distribution of information involving people, music, and other data. Jones developed the first plugins, and then opened an API to the community, after which many music players on different operating system platforms were supported. Audioscrobbler was limited to keeping track of which songs its users played on a registered computer, which allowed for charting and collaborative filtering.

Last. fm was founded in 2002 by Felix Miller, Martin Stiksel, Michael Breidenbruecker and Thomas Willomitzer, all of them from Germany or Austria, as an Internet radio station and music community site, using similar music profiles to generate dynamic playlists. The site name takes advantage of a domain hack using fm, the top level domain of Micronesia, popular with FM radio related sites. The "love" and "ban" buttons allowed users to gradually customise their profiles. Last. fm won the Europrix 2002 and was nominated for the Prix Ars Electronica in 2003. The Audioscrobbler and Last. fm teams began to work closely together, both teams moving into the same offices in Whitechapel, London, and by 2003 Last. fm was fully integrated with Audioscrobbler profiles. Input could come through an Audioscrobbler plugin or a Last. fm station. The sites also shared many community forums, although a few were unique to each site. The old Audioscrobbler site at the audioscrobbler. com domain name was wholly merged into the new Last. fm site on 9 August 2005. Audioscrobbler. net was launched as a separate development oriented site on 5 September 2005. However, at the very bottom of each of the Last. fm pages there was an Audioscrobbler "slogan", which changes each time the page is refreshed. Based on well known sayings or advertisements, these originally appeared at the top of the Audioscrobbler website pages and were all created and contributed by the original site members. An update to the site was made on 14 July 2006, which included a new software application for playing Last. fm radio streams and for logging of tracks played with other media players. Other changes included the improvement of the friends system and updating it to require a two way friendship, the addition of the Last. fm "Dashboard" where users can see on one page relevant information for their profile, expanded options for purchasing music from online retailers and a new visual design for the web site (including an optional black colour scheme). The site began expanding its language base on 15 July 2006, with a Japanese version. Currently, the site is available in German, Spanish, French, Italian, Polish, Portuguese, Swedish, Russian, Turkish and Simplified Chinese. In late 2006, the site won Best Community Music Site at the BT Digital Music Awards in October. Last. fm also teamed with EMI on Tuneglue Audiomap. In January 2007 it was nominated for Best Website at the NME Awards.

At the end of April 2007, rumours of negotiations between CBS and Last. fm emerged, suggesting that CBS intended to purchase Last. fm for about £225 million ($449 million ). In May 2007 it was announced that Channel 4 Radio was to broadcast a weekly show called Worldwide Chart reflecting what Last. fm users around the world were listening to. On 30 May 2007, it was announced that Last. fm had been bought by CBS for £140 million with Last. fm's current management team staying in place. In July 2008, the "new generation" Last. fm was launched featuring a completely new layout, colour scheme, and several new features, as well as some old ones removed. This was, however, met with dissatisfaction amongst some users, who complained about the "ugly and non user friendly layout", bugs, and slowness. Still, a month after the redesign a CBS press release credited the redesign with generating a 20% growth in the site's traffic. On 22 February 2009, Techcrunch claimed that "[the] RIAA asked social music service Last. fm for data about its users' listening habits to find people with unreleased tracks on their computers. And Last. fm, which is owned by CBS, allegedly handed the data over to the RIAA." This led to several public postings from both Last. fm and Techcrunch, with Last. fm denying passing any personal data to RIAA. The request was purportedly prompted by the leak of U2's then unreleased album No Line on the Horizon, and its subsequent widespread distribution via peer to peer file sharing services such as BitTorrent. Three months later, on 22 May 2009, Techcrunch claimed that it was CBS, the parent company of Last. fm, that handed over the data. Last. fm again denied that this was the case, saying that CBS could not have handed over the data without Last. fm's knowledge.

On 24 March 2009, Last. fm announced a change in free stream listening policy. According to the blog post "[ ] In the United States, United Kingdom and Germany, nothing will change. In all other countries, listening to Last. fm Radio will soon require a subscription of €3.00 per month." The change went into effect on 22 April 2009. The announcement led to a wave of disappointment among users, resulting in users stopping submission of their data, refusing to change signatures/avatars and even deleting their accounts. On 11 September 2009, CBS Radio announced that Last. fm programming would be available in four major market FM stations for the first time on their HD Radio multicasts. This includes KCBS HD2 in Los Angeles; KITS HD3 in San Francisco; WWFS HD2 in New York City; and WXRT HD3 in Chicago. The programming, which consisted mostly of music aggregated by Last. fm's user generated weekly music charts as well as live performances and interviews from the Last. fm studios in New York City, debuted on 5 October. On 12 April 2010, Last. fm announced that they would be removing the option to preview entire tracks, instead redirecting to sites such as the free Hype Machine and pay to listen MOG for this purpose. This provoked a large negative reaction from some in the Last. fm user community who perceived the removal as hindering the ability of lesser known and unsigned artists to gain exposure for their music and general enjoyment of the site. A new "Play direct from artist" feature was introduced soon after, which allowed artists to select individual tracks for users to be able to stream in full. The ability to listen to custom radio stations ("personal tag radio", "loved tracks radio") was withdrawn on 17 November 2010. This change provoked an angry response among users. Last. fm stated that the move was for licensing reasons. The change meant that a tag radio stream would include all music tagged as such, not just that tagged by each individual user, effectively widening the number of tracks that might be streamed under any one tag set.

In March 2012, Last. fm was breached by hackers and more than 43 million user accounts were compromised. The full extent of the hack, and its connection to similar attacks against Tumblr, LinkedIn and Myspace in the same time frame, were not confirmed until August 2016. On 14 February 2012, Last. fm announced that a new beta desktop client had been launched for public testing. The new scrobbler was released for all users on 15 January 2013. On 12 July 2012, Last. fm announced a new website redesign was also open to public beta and would rely on feedback from testing users. The site redesign went live for all users on 2 August 2012. While well received by technology websites, many of the site's users reacted negatively to the changes on the website's forum. On 13 December 2012, it was announced that Last. fm would discontinue radio service after January 2013 to subscribers in all countries except the United States, United Kingdom, Germany, Canada, Ireland, Australia, New Zealand and Brazil. Additionally, radio in the desktop client would require a subscription in the US, UK and Germany, although the website radio would remain free in those countries. Upon the introduction of the YouTube player, the standard radio service became a subscriber only feature. On 26 March 2014, Last. fm announced they would be discontinuing their streaming radio service on 28 April 2014. In a statement, the site said the decision was made in order to "focus on improving scrobbling and recommendations". On 15 April 2015, Last. fm released a subscriber exclusive beta of a new website redesign. Digital Spy described user reactions on the site's forums during the week of the redesign as "universally negative". In 2016, Music Manager was discontinued and music uploaded to the site by musicians and record labels became inaccessible; post Spotify integration they could still be played and downloaded where the option was given, but following the change artists themselves were unable to access their songs in the Last. fm catalogue. Last. fm celebrated its twentieth anniversary in 2022. Third party developers have built programs that integrate users' listening statistical data with Discord, including a popular bot from the Netherlands which has over 400,000 total users.

Last. fm Ltd is funded from the sale of online advertising space and monthly user subscriptions.

In 2004, the company received the first round of angel money, from Peter Gardner, an investment banker who was introduced to the founders as early as 2002. A second round was led by Stefan Glaenzer (joined by Joi Ito and Reid Hoffman), who bought into Michael Breidenbruecker's shares as well. In 2006 the company received the first round of venture capital funding from European investors Index Ventures, whose General Partners Neil Rimer and Danny Rimer also joined Last. fm's board of directors, consisting of Felix Miller, Martin Stiksel and Stefan Glaenzer (chair). Original founders Felix Miller, Martin Stiksel and Richard Jones left the company in summer 2009.

The free user account includes access to all the main features listed below. Registered Users are also able to send and receive private messages. The newly launched last fm pro user account adds additional features to the free tier, most notable being the ability to change username and early access to new features.

A Last. fm user can build a musical profile using any or all of several methods: by listening to their personal music collection on a music player application on a computer or an iPod with an Audioscrobbler plugin, or by listening to the Last. fm Internet radio service, either with the Last. fm client, or with the embedded player. All songs played are added to a log from which personal top artist/track bar charts and musical recommendations are calculated. This automatic track logging is called scrobbling. Last. fm automatically generates a profile page for every user which includes basic information such as their user name, avatar, date of registration and the total number of tracks played. There is also a Shoutbox for public messages. Profile pages are visible to all, together with a list of top artists and tracks, and the 10 most recently played tracks (can be expanded). Each user's profile has a 'Taste o Meter' which gives a rating of how compatible the user's music taste is.

Last. fm features a personal recommendations page that is only visible to the user concerned and lists suggested new music and events, all tailored to the user's own preferences. Recommendations are calculated using a collaborative filtering algorithm so users can browse and hear previews of a list of artists not listed on their own profiles but which appear on those of others with similar musical tastes.

Once an artist has had a track or tracks "scrobbled" by at least one user, Last. fm automatically generates a main artist page. This page shows details of the total number of plays, the total number of listeners, the most popular weekly and overall tracks, the top weekly listeners, a list of similar artists, most popular tags and a shoutbox for messages. There are also links to events, additional album and individual track pages and similar artists radio. Official music videos and other videos imported from YouTube may also be viewed on the relevant artist and track pages. Users may add relevant biographical details and other information to any artist's main page in the form of a wiki. Edits are regularly moderated to prevent vandalism. A photograph of the artist may also be added. If more than one is submitted, the most popular one is chosen by public vote. User submitted content is licensed for use under the Creative Commons Attribution Share Alike License and GNU Free Documentation License. Last. fm currently cannot disambiguate artists with the same name; a single artist profile is shared between valid artists with the same name. Also Last. fm and its users currently do not differentiate between the Composer and the Artist of music which serves for confusion in classical music genres.

One particular feature of Last. fm is the semi automatic weekly generation and archiving of detailed personal music charts and statistics which are created as part of its profile building. Users have several different charts available, including Top Artists, Top Tracks, and Top Albums. Each of these charts is based on the actual number of people listening to the track, album or artist recorded either through an Audioscrobbler plugin or the Last. fm radio stream. Additionally, charts are available for the top tracks by each artist in the Last. fm system as well as the top tracks for individual albums (when the tagging information of the audio file is available). Artist profiles also keep track of a short list of Top Fans, which is calculated by a formula meant to portray the importance of an artist in a fan's own profile, balancing out users who play hundreds of tracks overall versus those who play only a few. As the information generated is largely compiled from the ID3 data from audio files "scrobbled" from users' own computers, and which may be incorrect or misspelled, there are many errors in the listings. Tracks with ambiguous punctuation are especially prone to separate listings, which can dilute the apparent popularity of a track. Artists or bands with the same name are not always differentiated. The system attempts to translate some different artist tags to a single artist profile, and has recently attempted to harmonise track names.

Last. fm generates weekly "global" charts of the top 400 artists and tracks listened to by all Last. fm users. The result is notably different from traditional commercial music charts provided by the UK Top 40, Billboard, Soundscan and others, which are based on radio plays or sales. Last. fm charts are less volatile and a new album's release may be reflected in play data for many months or years after it drops out of commercial charts. For example, The Beatles have consistently been a top five band at Last. fm, reflecting the continued popularity of the band's music irrespective of current album sales. Significant events, such as the release of a highly anticipated album or the death of an artist can have a large impact on the charts. The Global Tag Chart shows the 100 most popular tags that have been used to describe artists, albums, and tracks. This is based on the total number of times the tag has been applied by Last. fm users since the tagging system was first introduced and does not necessarily reflect the number of users currently listening to any of the related "global tag radio" stations.

In addition to Last. fm automatically tracking music played via Last. fm's radio, users can also contribute (scrobble) listening data to their Last. fm profile from other streaming sites or by tracking music played locally on their own personal devices. Scrobbling is possible with music stored and played locally via software on devices such as PCs, mobile phones, tablets, and standalone (hardware) media players. Indeed, these were the only methods of scrobbling listening data both before and after the existence of the Last. fm radio service. Certain sites and media players have the ability to upload (scrobble) listening data built in, for others users must download and install a plugin for their music player, which will automatically submit the artist and title of the song after either half the song or the first four minutes have played, whichever comes first. When the track is shorter than 30 seconds (31 seconds in iTunes) or the track lacks metadata (ID3, CDDB, etc. ), the track is not submitted. To accommodate dial up users or those listening to music while offline, caching of the data and submitting it in bulk is also possible.
