He’s beating those drums like they owe him money

This, in my opinion, is what defines heavy metal. It's a crossroad in terms of heaviness, adrenaline, sinisterness, epic, etc.

I'm currently a med student and once i become a doctor , I'll prescribe this song to any iron deficiency patient i see

there's enough metal in this song to build the fucking death star

For me, the guitar solo in this song is one of the best not only in metal but also in rock in general in all of history.

This is, quite literally, the single best heavy metal song ever written.

That's so fucking metal all the refrigerator magnets came into the living room to see what was going on.

One of the best metal songs to ever exist.

Absolute madness. One of the best songs in the history of humankind.

The drummer on this song is “half man and half machine”.

So much metal in one song it's cured my iron deficiency

"So yeah, I'm the new drummer, this is my first day, glad to be here. Say, I have an idea for an intro to the title track. How 'bout this?" - Scott Travis

The best guitar solo in heavy metal history

Iconic drum intro. If you've never air drummed to this, you're lying.

Saw Judas priest this summer, lead singer age 72, still fucking sounds like this. Fucking unreal performance. I bow my head in pure respect for one of the greatest metal bands ever to exist.

A metal song without enemies. Regardless of your taste in metal, everyone can gather around Painkiller.

This is not a joke, but when I moved out to go to college my roommate and I had an insane woman in the apartment underneath us. She would lose her mind any time either of us would make any noise of any kind, like walking, doing dishes, etc. Well, during the times when she would REALLY get on my nerves yelling and screaming at us, I would just turn my surround sound system on with the bass up all the way and blast this song. Every time it was over she would be COMPLETELY quiet EVERY SINGLE TIME.
