This thing also has one of the biggest fuck you’d from Blizzard. Once you get the jukebox, you can start collecting ones from raids. One of them is in ICC, off the Lich King. It’s also called... Invincible. So imagine my reaction when I was 1 song roll away from completing the 10 rolls achievement and get the invincible track. Thinking it was the mount.
if you have sylvanas' music box (toy box item) you can also use that and summon the lamenters to sing the song wherever you are. which gives you creepy banshees to float around while they sing. i have too many toys in WoW >_>
