Am I the only one who doesn't know how to do this?

So I have an iPhone 4s. And a lot of my friends have them too. They all have music on their phones and I ask them if they pay for their music using iTunes and they said no. I don't know how to illegally download music? I use playtube, but I actually want to use the real music app. I'm kinda embarrassed that I don't know how to download music without using iTunes or paying for it.

Do any of you know?

Some friends you got.

Download " Free Mp3 " from the app store. It's unlimited music downloads. It's the best music app. Search for the music your looking for on google. Ex: " Pink - Just Give Me a Reason free download " & you'll find what your looking for.
