You don't XD

Listen to metallica. Hetfield is waaaaaaaaay more interesting than that girl pretending to be a dude.

You have managed to insult his music at every chance you get but when you insult him that's when I lose my shit.

Sounds like a personal problem.

No you've turned it into a problem between both of us.

Honestly, best advice now: I doubt this is reversible, but listen to his music daily 24/7 until you get tired and sick of him

I'd imagine it's similar to smoking weed, after a while you build up a tolerance. If you stay away from it long enough, when you try it again, you will get fucking BLOWED.
So @kouyaaotsuki 's advice might actually work out okay.
