So far this app is just ok. I really wish Google didn't get rid of Google play music, it was far better and worked perfectly. Not sure why on this app all of a sudden your device files don't show up when you search? Definitely needs some better integration with the songs you add or purchase and the device files I think. Update 2022, something is not working right when I'm playing music on Bluetooth, it will randomly stop in the middle of a song
