7.0.5 iPad iOS - Cannot Play Music on Bluetooth Earbuds

I use Bluetooth earbuds with noise reduction to play music from my apple playlist while exercising. Since the upgrade to 7.0.5 I cannot do this as soon as I start the ride the music app stops playing. If I pause FulGaz to restart the music app, FulGaz freezes and have to restart.

Having a few tunes playing while exercising certainly takes the edge off. Can this functionality be incorporated into I the new version please.
