IPhone app music not working

I just changed the battery in my iPhone 4 because the previous one was not working and now in just a few of my apps the music doesn't work but the sound does
e.g. In temple run you can still hear the character jumping and stuff but you can't hear any background music.

Is this because I changed the battery or what?
Thanks

Added (1). I only changed the battery because it had water damage

Sounds like your iPhone 4 is on the way out, sorry: x

  • Music on iPhone 4S not working? It started a couple weeks ago when all my album art was turned into a music note, which wasn't a big deal so i ignored it. But now when i press play, it shows that music is playing but no sound comes out and the volume slider disappears (the buttons don't work either). I hadn't downloaded anything before the changes occurred. Does anybody know how i can fix it? I have an iPhone 4S with the lates version of ios
