Jukebox Sulfur Cube

If you give a Jukebox to a Sulfur Cube, you can also feed it an additional music disc to play it. Each music disc will have a special effect that triggers when played but it will be destroyed afterwards.

Maybe the Pigstep disc could boost the chance of rare items from Piglin trades, or the 5 disc could de-spawn any nearby Wardens or disable skulk sensors. 

One idea I really like is having one of the music discs inhibiting an Evoker's magic, and every time they try to summon a Vex, the Vex will be frozen in place and slowly turn into an Allay.
