Has anyone else been using this?
Essentially, it's like last.fm meets itunes. You can instantly stream whole albums for free, and there's no catch except for the occasional directgov advert and the medium bitrate (which is more than acceptable if you're at work and listening on tinny little speakers anyway).
It's still in beta, but I think it's going to be marketed as a legal and easier alternative to illegal downloading. Obviously it doesn't have super obscure stuff on there, but today i've been listening to Low, Minutemen, Sufjan Stevens, Chet Baker, Mogwai, Black Flag...
