I'm having a similar issue. I was messing around in my survival world, and I took my music disc (C418 - Cat) out of my jukebox and put it back in over and over by holding right click, but when I tried to take it out at the end, I got the item back and my parrot stopped dancing, but the music sound kept playing. I tried closing my world and re-entering my world, but the music was still playing even when I was on the title screen. I also tried putting a different music disc (C418 - 13) in the jukebox, but that caused both sounds to play at the same time. Finally, I completely closed the game and re-opened the game and then the music stopped.
Some things to note:
I was using a vanilla 1.12.2 client with the regular amount of allocated ram
