I'd have to agree with this also. It's called YOUtube for a reason, it was created for YOU to upload videos of YOUR content. If Grooveshark was called YOUshark or something in the beginning, and stated: Upload YOUR bands recordings and get exposure! This would be a different thing. Back when Grooveshark was starting out they could assume that James Taylor and U2 were not uploading their content to get exposure and could have deleted that manually at the beginning to try and enforce their point that it is unsigned content only. But that's not what they are going for.
