Boss music

We need boss music for raids, the wither fight, and ender dragon fight. We need these sounds because I feel as if it would make the fights more dramatic and it would probably make the player feel more immersed into the game. Because right whenever you are fighting the major bosses or doing a raid it feels kind of underwhelming and not as dramatic as you would have expected it to be if you have never fought the bosses or done a raid yet.
