My (Full featured/bought) Poweramp on my Sony Xperia ZL has a weird feature. Only in my car (Ford Focus) it starts playing via bluetooth, so far everything is ok. At the start of a new song within a second pause is pressed (actually visible) and immediately pressed again so the song continues. Problem is you have a second interrupt. This only happens with setting CyanogenMod Metachanged Intent on the selection 'Sony #3' in the bluetooth settings of Poweramp. I've selected this setting because only with this setting the song and artist info is shown on my car display. If I select any other option the info is gone, but the strange pause behaviour is also fixed.
