Ender dragon music disc.

The Ender dragon is one of the most iconic bosses in video game history, and i find it confusing that it does not have its own music disc, while the Sulfer Cube does.

I think the Ender dragon should drop its own music disc upon death, being another reward for killing it. Since you can respawn the Ender dragon and thus kill it again, people would have access to the disc even if another player has taken it.

The disc itself.
I think that the disc should be an representation of the dragon's life, starting as a slow classical like tune, representing its birth and early life. In the end its an orchestral piece like Overture 1812, representing its battle against the player and its death.
