Pause Menu Background Music!

Make when opening the pause menu a music track would play in the background, it could be paused/resumed when opening/closing pause menu /and while scrolling through settings, would be super nice and chill, everyone would like it, and it can use sounds and sound_definitions so programmers can make their own tracks, like no need to hire or ask a music composer, i just really hope to this just be available as a sound in sound definitions in the game in code so it can easily be modified and add our own tracks in a local resourcepack.
