On the Nintendo Switch and iOS devices, after inserting a disk into a jukebox and the player destroys the Jukebox without removing the  disk, the music will continue playing. The music will stop once the disk ends or until another block is placed in the same location the Jukebox was. It is possible to get more than one disk playing at a time using this method. I only tried this in Creative Mode in Bedrock 1.12.0 and Bedrock 1.12.0 with Experimental Gameplay enabled.
