History originated from the two sides and

Audioscrobbler began as a computer science project by Richard " RJ " Jones at the University of Southampton in England. Jones developed the first plugins, and opened the application programming interface ( API ) for the development community, after many music players were supported on different operating system platforms. Audioscrobbler was limited to, logging played on a registered computer music, which allowed Charts and collaborative filtering. was founded by Austrians and Germans Felix Miller, Martin Stiksel, Michael and Thomas Breidenbrücker Willomitzer as an internet radio station and music community site in 2002 and went out of Netlabel " Insine " out. The music profiles of different users are compared and used the thus determined similarities to generate dynamic playlists. So the musical taste of the listener should be taken as closely as possible.

TechCrunch on the basis that an informant, which at CBS - would work - the owner of This would have testified that the RIAA would get handed users, the IP addresses that the at that time available only as an illegal copy album No Line on the Horizon for the band U2 " scrobbled " - and there have therefore procured illegally. denied the allegation vehemently; The co-founder Richard Jones described the accusations as rumors and defaming TechCrunch in his blog with the words " Techcrunch are full of shit " TechCrunch after and published put another article in which re- statements of new informants were listed, the disclosure of personal data by CBS confirmed.

Event System

Since October 2006 there is an event system. It creates the user with an automatic list of concerts based on the music user's profile. In addition, the user can easily add your own events. The interaction between users should thus be strengthened, because you can see what other users have attended the same concert and want to visit.

In March 2007, the event system has been developed to make larger cities directly via the link accessible.

Video channels

On May 17, 2007 Music Videos were introduced on the English side, and now (2008) they are also available in the German version. Now music labels and bands to upload music videos in the system. The restriction on labels and groups is so not like YouTube is coated with copyright lawsuits. The videos are at a bit rate of 128 kbit / s encoding (current default YouTube: 64 kbit / s). There is now also a tab for music videos on the band and track pages. The aim is to offer analogous to radio video channels. The user personalized music video streams are thus shown.


The system of allows you to " scrobble " tracks unknown artist by the fact that they are newly created, if required. Due to the manual tagging of songs created for so many artists, albums and songs different spellings, which can often be inadequately compensated by the software and thus, among other things distort statistics. now prevents the front with the so-called fingerprinting; this is a technique that determined independently of the metadata a unique ID of a track to scrobble tracks correctly. This allows to assign correct spellings and to clean up the catalog data ( so, for example, "Simon and Garfunkel " and " Simon & Garfunkel ", both a notation assigned ).

The desktop application reads the fingerprint of a title and transmits it. For new unknown songs, the software must determine this first, and then transmits it. The source of the title is not transmitted, and a change of, for example, MP3 files will not take place.

Known Issues the system is not able to distinguish the same artist; their interpreters pages are bound together.


After a certain time without any interaction on the page breaks for the undeclared users regularly from the music sequence. A panel prompts you to log in to Then the user needs to log in or, if he does not want to, new dial. The duration at normal users an hour, while subscribers may listen to the page radio six hours without any interaction. This restriction only applies to the Flash Player, which can be used. When using the client or other software, this restriction shall not enter into force.
