The jukeboxes need to be improved. There should be a GUI when you open it, with different options. There are 7 slots for music discs. Then there is a pause button and a play button. Then there are several options options- select disk, continuous, and shuffle. You cannot remove the disks unless you placed the jukebox, or maybe a gamerule to change that. There should be a face on the block that shows what disc is playing, and an animation of the disk spinning. If you open it while a disk is playing, It says "Now playing: C418- Cat" or whatever song is playing. It should also say what's up next and what was previously played.
I don't know a website where I could make a GUI, so I don't have any pics.
