I don't mean to be saying it in "go buy a new keyboard way", but a lot keyboards out there have a nice array of possible buttons across the top, and work withs tons of musicplayers out there. I have a simple $20 keyboard which makes it easy to play, stop, pause, next/prev track, and even a button to open default music player.
I know this isn't as easy as picking a song or playlist from in-game, but it works
