Looking for an excellent mp3 player app

[EVJWinters]

I am using a BLU Studio X phone with Android 5
I am looking for a reputable mp3 app which has the means to:
- build playlists, back up playlists, and recover playlists.
- user assigned paths to music files
- equalizer
- remove songs from playlists without removing songs from phone storage
- remove songs from playlists AND remove songs permanently from phone storage
- playback songs in listed order, shuffled, and continuous loop

What recommendations might anyone have for me?

Have you tried PowerAmp?

It is not as pretty as some music player apps, but it is still one of the very best.

PowerAmp is one of the best. UI is bad though.

I wouldn't say "bad" - but it is dated and plain.

On the other hand, who cares? I start up a playlist and then move on to other things; I don't sit there staring at the screen.

PowerAmp's good points far outweigh the bad.
