Need to a silence music option

I have been working out with this app for the past month now and have definitely seen positive results. At first of course, it feels pretty intense but after the 2nd or 3rd work out I could feel my muscles were getting strong enough to keep up. I also like that it connects with my Fitness pal so it helps me count my calories. However one major thing that would make this app 100% better is an option to silence the music. I know that the runtastic running app allows a person to run, with the voice alerts and also listen to other music from another app at the same time. I wish the app designers would make this consistent with all of their apps. Other than that this app has really made a positive impact on my health. Thanks!
