Use Pigstep for the Wither Boss Fight

The title explains itself, if the Ender Dragon can have boss fight music that fits the mood of the boss fight (despite being re-used), and sounds excellent, then why can’t we get something similar for the Wither?

It’s virtually a fact that it doesn’t work very well to have regular ambient and peaceful Minecraft music (or just plain silence) during a intense fight like this, and Pigstep certainly fits the bill of the boss fight. 

Just imagine the bass drop (I think that’s the terminology) happening right after the Wither is done charging up. Pretty fancy stuff.
