Maybe you might consider to do a few (I think) simple improvements for the jukebox?
- If the game went to windowed mode when selecting jukebox or something it would make it a lot simpler to switch to and from so one could change music and then listen in the background.
- A start/stop button would be nice, in case I want to listen to something else for a while (eg: youtube video.)
- Having the game in the background or minimized won't stop it from keeping the resource usage high. I guess the rendering is still going on for nothing. Can that be disabled if the game is not in front?
- Separate volume control would be nice. In-game I don't want too loud music, but while listening to it I usually want it louder.
