Spotify is a DRM-based music streaming service offering unlimited streaming of selected music from a range of major and independent record labels including Sony, EMI, Warner Music Group and Universal with virtually no buffering delay. The system is currently accessible using Microsoft Windows, Mac OS X, Linux and mobile devices such as the iPhone and those running Android, Symbian, Windows Mobile or Palm's HP webOS.
Music can be browsed by artist, album, record label, genre or playlist as well as by direct searches. On desktop clients a link allows the listener to purchase selected material via partner retailers. Launched in October 2008 by Swedish startup "Spotify AB", the service has approximately ten million users as of September 15, 2010; about 750,000 of these are paying members.
Users can register either for free accounts supported by visual and radio-style advertising or for paid subscriptions without ads and with a range of extra features such as higher bitrate streams and offline access to music. A "Premium" account is required to use Spotify on mobile devices.
Spotify is currently available only in certain parts of Europe, with paid subscriptions restricted to people with credit/debit cards or PayPal accounts registered in particular countries.
Note the free membership is only 20 hours of free music, very easy to create an account, just username and password.
