Amazon rules the "legally free MP3" arena. Not only do they have hundreds (600+) of free songs in their library available anytime, they started doing a "free song of the day". Great business idea for them, and more free music for us! Along with that, they started doing a "cheap album of the day". I recently got the new White Rabbits album for $1.99. Can't go wrong at that price!

No, I'm not an Amazon employee. Yes, I'm a huge Amazon fanboy. :)
