How to get music to your iphone 5 music library without conecting to a pc or itunes?

The problem is i don't havd my laptop ( which contains my itunes library) with me since i'm travelling.
I need to download some music!
And no my iphone is not jailbreaked.

So is there any methotd?

Unfortunately not, you would need to sync the library on your laptop with another computer's library (Home Sharing). Kreeble is a good (legal? Maybe?) app for downloading music, though!

You can use the itunes app on your phone to download songs you purchased or to buy new songs
