I only discovered Poweramp last week, and I must say that I'm very impressed! Ease of use, sound quality, responsiveness, it's a hell of a thing. I've been using it with my car's BT audio controls. Most of the controls work, but a few don't, and I don't know if there's something I'm doing wrong, or if it's just something that hasn't been implemented. The car's audio controls include folder navigation buttons as well as random and repeat buttons. These don't seem to have any effect on Poweramp. Should they? I haven't tried fiddling with the single/double/triple press settings, but I think it'd be neat if the folder controls would be recognized. FYI it's the stock stereo that came in a 2013 Corolla.
