I like stock music apps best. I have an old 5.0 Android Samsung tablet which does well with Android Auto. The latest Android Auto now has old cast built in, and corrects screen formating with Samsung Music. Samsung Music now has better controls with full browsing features. I assume the same with Sony Music... Which we all know can be flashed with full features to any device, using magisk or as a twrp installer. Be sure to update the Plugins to make it full featured.
Apple Music. Love that I can stream tracks from Apple, I can upload my own MP3s to iTunes and have them on my app and I can play my Playlist. This is a combination no other music app gives. Works great with AA as well.
