Google Music offers at least 106 MP3 downloads
. It's tied with yesterday's similar offer as one of the best collections of free MP3 downloads we've seen. It includes songs from artists such as Ben Folds Five, Usher, Alabama, Kenny Chesney, John Mayer, Janis Joplin, Train and more.
You may need Gmail and Google Wallet accounts to access these free downloads. (There, you'd need to provide a credit card, but you won't be billed.)
