I love this idea and thought I would just share !
http://www.freeallmusic.com and http://www.Guvera.com are two places to get FREE music Legally. There are some hitches but it might just be worth it. I have not set up my accounts yet but after reading about it I like the idea.
FreeAluMusic.com you have to watch ads to get the the music. Not a bad deal heck we have to see ads anyway might as well get something for it right !.
Guvera.com you have to do surveys to get the music. Advertisers basically for you to be able to download.
Hope this keeps a few bucks in your pocket !
