I would like to use Poweramp as music player in the list of audio players in 3rd party applications (like Endomondo). I know that there are other 3rd party applications that can use it. Since I have installed MortPlayer for my audio books it is listed in Endomondo (or other apps like runtastic). Poweramp is a great program and I bought the Pro version so I think it should have this option. In an other thread I read about permissions, but this feature should not need a lot of permissions. I would be very great-full, you can implement this feature.
