Re: what's the best music app?
If you dont need fancy display, like album art support to play your music then you can try the built in ES File explorer on the player
It can play your favorite music folder by choosing "play" and at the same time you can add music file from different album by choosing "add to playing" option. Hope you can try it.
-Browse for your music file
-Hold and press the "select" button from the remote.
-Choose Add Music
-Choose "Play" or "Add to playing"
