Boss music

[LardMcLovin]

Hey, so I have something specific. I need a boss music song with lyrics. I was going to use five finger death punch or ozzy Osborn. Thing is, I cant decide what from FFDP and I need something hard from ozzy. It's a boss fight against a possessed biker gang leader, who turns into a demon in a second phase. Instrumental in the first phase and lyrics in the next. That's what I'm looking for. Any suggestions?

Bark at the Moon and Rock n' Roll Rebel are the first that spring to mind. I'm sure you'd be able to find an instrumental version of either to use for phase one then switch to the full song for phase two.

Just speaking for myself, if Bark at the Moon started blaring at the start of a boss fight I'd be pretty pumped.
