IPhone 4s music library problem?

OK so my family and I are currently on vacation, it is about an 8 hour drive to get from our home to the beach that we go to. So I listen to my music on my IPhone while riding in the car.

here's where the problem arises, while listening to my music i play games on my phone and certain apps when opened shut off the music playing from the ipod.once the music is shut off by the app when i turn my music back on it starts the music back from song 1. Because i keep my ipod on shuffle i heard the same songs multiple times on the way to the beach and hope to have the problem fixed by the time we leave next Saturday.

If there's anyone that had a similar problem and fixed it, or just someone that knows how to fix the problem can you help me out?

The issue is that there are certain apps that stop other processes so they can run their thing. In the case of the music, it's probably because there's music in the game and they don't want it to overlap with your music. Maybe try disabling the music in the game and see if that does anything
