The song crossfaded to another and now i hear two songs at the same time. I have no idea what's going on but i paused it and both songs pause and then unpause then both songs start playing again. This is weird. I think that happened once before. It seems it was playing the previous song at the same time. Skipping forwards to the next song and back fixed it.
I'm using a Galaxy 9+, Galaxy S7, a Galaxy Tab S 8.4, Poweramp, and Musicbee.
