What happened to the music!?!

I had this game for a long time on iPhone 4, and the best part about the game was the awesome music! But today I downloaded on my iPhone 6 and theres no music. The settings said music and sound were on (the sound effects worked fine) but there was no music! I even deleted and redowloaded to try to fix it but to no avail. Apparently Im not the only one with this problem either. Please fix it
