If you love FREE music like I do check out VolumeVote. They offer a new FREE music download everyday and today's (8/16) song is California Gurls by Katy Perry featuring Snoop Dogg.
From what I understand, VolumeVote usually offers songs from lesser known artist but sometimes they do offer the more mainstream artists. - worth checking out.
Thanks goes to Deal Seeking Mom for the heads up on this freebie.
