My iPhone 5, won't let me play a certain song that I played last night?

It won't won't let me play it or delete it. It just skips it. I tried turning my phone on sleep mode twice. It did that with the note app, it just would randomly erase my notes. It started wroking again today, but now my music! If i press the home button and the power button at the sane time, will that erase all my content?

LOL Really>?/? CALL APPLE THEY MADE THEM LOL

Nah man, it won't erase your content, it will just turn the device off into some kind of DFU mode. It's just okay.
But why do you want to do it?
If I were you, I would backup the content, then restore the iphone from itunes
