Great, but messes up my tunes!!

I loved this app for the first two months...it worked perfect. But then my music started turning off and on/fast forwarding, etc. Then my SIRI started activating constantly during my run (very frustrating!). I thought it was the phone and even went as far as exchanging my phone with Apple. Now it is happening again. I can only think it is the Higdon program because it only happens when I run. Please fix the bug!
