[DISCONTINUED] On December 8, 2009, MySpace (owned by News Corp) acquired imeem, closed down the site and all users were redirected to MySpace Music. It was a free to use web app to listen songs from their database. The database was quite large, and You didn't have to register to listen to the songs. Registration was required for creating personal playlists, giving comments etc. More info »
Yeah I really liked it but now I use Lala.com instead of imeem, and Mufin.com for finding new songs.
This WAS a great platform... until MySpace bought them up and shut it down. :(
Whenever I am looking for a song to get or just trying to identify a song I use this a lot, it has very nice audio quality. So if you want to here a good version of a song, listen to it here rather than youtube or something else.
