Spotify

Developed by Swedish company "Spotify AB", the software allows unlimited streaming of selected music from a multitude of major and independent record labels including Sony, EMI, Warner Music Group and Universal with virtually no buffering delay.

An ad-supported version of the software is free to download in Sweden, Spain, Norway, Finland, France, the Netherlands and the United Kingdom; for a monthly fee, users can upgrade to a "Premium" account, which offers higher bitrate streams, offline access to music and use of Spotify on mobile devices running iPhone OS, Android or Symbian.

Music can be browsed by artist, album, record label or playlist as well as by direct searches, and a link allows the listener to purchase selected material via partner retailers. Launched in October 2008, Spotify has approximately seven million users as of May 19th, 2010; about 250,000 of these are paying members.
