I don't know if i'd use it now but several years back I downloaded so much from it and got me into so much stuff which led onto other things. Download a song by an artist, then look at similar artist bit down the side and go through loads of bands.

got me into Angel Hair, VSS, The 1985, Black Dice, Ruins, Song of Zarathrustra, Drive Like Jehu, The Locust and they'd get me into many more.

I don't know if it would still work the same nowadays but it used to be one of the only things that go me into that type of band.

So, anyone else use it? Get you into anything you still listen to today?
