I've recently installed Poweramp on my Android 4.4.4 car head unit (JY) and it has one annoyance - if the song being played don't have album art, the screen is mostly blank with "Poweramp" in the centre. I was surprised to learn that Poweramp has no option for a spectrum analyser or visualiser. Can anyone recommend an decent alternative music player which has a spectrum analyser rather than a mostly boring looking blank screen?
