What is a free app to download music on a iPhone 4?

I have a iphone4 and I would like music on it. But I don't want to pay for music. I'm just wondering is there a free app that you can download music straight into your music library

I hope someone answers you. Cause I have been having the same question/

Apple's Mobile Devices are nothing more than EXPENSIVE Marketing Tools to sell Media Content from iTunes, period. And sadly, it IS working…

So, if you Really want more freedom, stop BUYING Apple Mobile Devices. And, the best reason for that is: iTunes is the worst App I've ever tried to use.

I think I'll continue to use my 6+ year old Creative ZEN for a few more years, thank you very much…

Apple Wants your money, They would never allow an app that gives you free money… Android would
