Is There An App To Download Music To Your Music App On Your iPhone?

With a computer

Yeah. Try the itunes store. You can access it on a apple computer and your iphone. They also have movies and stuff. But i don't think there's a app. Try searching "free music" in the app store. Hope i helped.

No apple makes sure that there's no other way to download free muic directly to your ipod you. Will have to do it from your computer and then import the files to itunes that way
