Every Sunday we collect the best free music we can find and put it all in one place for a weekly feature called "10 Free Songs You Should Download Right Now." Since it's the last Sunday of 2012, we decided to go all out. There was no shortage of free music this year, and artists—especially up-and-comers—started to realize the value of giving some songs away. So here you go, 50 free songs you should download right now. Enjoy.
