I share my bad experience with poweramp music player. When I install it then I found that the music player theme is good and it play background also but one of the most important thing that there is some file format which not supported like(wav, lower range MP3 etc) these are not working so I contact to company for this inquiry they says that developer working on it so must wait sorry.
So my experience with my personal opinion that don’t install it or use it because I found that the something application is restarts automatically use any other music player such as VLC media player in which I found that every format is supported.
