I know next to nothing about mp3 blogs, but I just found a very cool site from which I can stream music while I work. It's a very eclectic mix, and I find that I don't like all the tracks, but it's got everything from Kenny Rogers to Guns and Roses to Radiohead - both Independent music and RIAA crap. Okay, it's not all crap. It seems that the site pulls from dozens of other mp3 blogs to gather content. Very nice.
