In my line of work, I get to trawl myspace, last.fm and other music sites on a daily basis. I love http://rcrdlbl.com and you might too!
I discovered Miss Kittin (http://www.misskittin.com/) through here and have recently discovered the beautiful vocals of Alela Diane (http://www.myspace.com/alelamusic) and Diane Birch (http://www.dianebirch.com/) here. Great place to discover new bands you’ve never heard of and also sample their music because they have mp3s for download!
Here are some tracks I downloaded from the RCRD LBL site.
