Best iphone app for free music?

I hate spending money for each song i buy on itunes. What is a good app for iphone where i can download free music. I don't mind paying up to $2 for the app. But i don't wanna pay every month for it, or pay for the songs. Thanks!

(i want something that has a huuuge variety of songs so i can get pretty much any song i want)
