I totally WOULD want this, but, you know, don't play hoovy.
I'd like it to be on my MediGun though. (or Don't Stop Me Now, that's a good one to have as well)
they should have a skin for the weap that looks like an old gramaphone then have the ammo barrel spin and shoot bullets while playing that song. the ammo barrel is a record and the bell is the barrel of the gun. and it should spew music notes long side with bullets.
