Portable music device?

Was exploring..an stumbled upon a music speaker, and got me thinking I would love a lil device, why not do an update that gives us a music device that gives us the option to make our own soundtrack.. I mean, the music is already there in the game. the bars, The exploring music, etc they have the music for it.

Yes I know there’s some mods for it but my play through is “vanilla” some paid creation.
