1.20 introduced jukebox automation.
Contrary to existing designs, this design can play multiple song based on user’s inputs. After a song is finished playing, another from the allowed list is automatically starts.



Two designs are present within the world save. The left one is slightly bigger but can handle disc queuing. Discs are played without time in-between and cannot be played twice in a row (multiple discs in queue).



In any case, you can choose what song can be played using the control panel. The top lamps are used to display what dropper are empty / to know what song are wating in the queue.



To stop the playlist, turn on the ‘stop playing’ option. The queue will be played but not replenished.To start the jukebox, turn off ‘stop’ option and push the wooden button. Once the redstone lamp stops blinking, you may press it again to add a disc to the queue (only for the design on the left).




PS : as Relic and Otherside share the same signal strength, they are not separeted. This will be the case for future music discs.
This Map was built on Minecraft Java Edition 1.20.1. It should be compatible whith later versions (if no major redstone change)
