What's a good music app for iPhone 5C?

I've about used all my data on my plan watching YouTube I need a good app that I can listen to current music. I tried pandora, but when I want one certain song it just randomizes it by artist. What about itube? Does that use data? Or is just a good music app?

I would have suggested itube! You use data to listen to the song once and then you can listen to it as many times as you want for free! So if you get Wi-Fi load up your songs and then you can listen when you don't have Wi-Fi
