8tracks

Not sure if this is supposed to be said 'Eight Tracks' or 'Infinity Tracks' (as their logo suggests) I'm guessing the latter as this site basically allows you to click 'Play' and just listen to music continuously.

Set into playlists created by users (as far as I can tell) you can make an account and save your favourite playlists. It is like Playlist.com except it allows you to find music you didn't really know before much more easily.

Take a look, I don't think you'll be disappointed: http://8tracks.com/

As always, hit up ekobor if you want to see what I'm up to.
