Recently my iphone has been getting songs I never bought downloaded?

It seems that they downloaded on their own, and when I looked them up, I couldn't even find them in itunes. Moreover, when I try to delete them from my phone it doesn't even give me the option to do so. I've heard a little about this problem before, but I can't seem to find any fixes for it. Any ideas?

Random Music Showed up on IPhone?

So I got a new iPhone about two months ago, and I only downloaded 7 songs on it. Tonight a whole album of U2 songs appeared in my songs list. I have never bought any U2 songs on my phone or any other apple device, and my phone is set up with my Apple ID that no one else uses! Did my iTunes account get hacked? (And I'm sure it's not iTunes Radio) but does anyone have an explanation?
