How to listen to music while playing hill climb on the IPhone 4?

Is there a way to liste to music from your iPod and be able to play hill climb and listen to music at the same time? I turned off the hill climb sounds and music and tried it but my music would turn off as soon as I played the app. Anyone know how to listen to music at te same time?

I play hill climb listening to music all the time. Maybe see if there's a newer version of the game?
