You're talking about power metal, so why is it only now that Manowar is being mentioned? They've probably been playing it for longer than anybody else and still are one of the greatest power metal bands ever.

On that note, check out Swordmetal.com if you like that type of music.

Black Sabbath
Dio (kick ass)
Judas Priest
Led Zeppelin
Motörhead
Mushroomhead
Ozzy Osbourne

Those are all decent metal bands, not overly heavy though. For some very heavy music (these probably don't all fit your requests, but I'm listing them just because they're metal) check out:

Agent Steel
Anthrax
Cannibal Corpse
Destruction
Exodus
Kreator
Lamb of God
Megadeth
Metallica
Pantera
Slayer
Testament
Venom

These are mostly older bands, all of them are pretty decent by some standard or another. A few aren't very well known compared to others. I doubt you'll like some of these, but again, they're all metal and they're all good.

I can't thrash to them, they're too damn happy.

I agree completely with you there, it's a good band, but not the type to headbang to.

1. Motorbreath - Metallica
2. Madhouse - Anthrax
3. Iron Man - Black Sabbath
4. Battery - Metallica
5. Raining Blood - Slayer
6. Peace Sells - Megadeth
7. Thunderstruck AC/DC
8. Fucking Hostile - Pantera
9. Walk - Pantera
10. Through Fire and Flames Dragon Force

Yeah. Heavy metal and the like, it all rules.

I'm not sure if it helps, but Lovin', Touchin', Squeezin' by Journey comes to mind.

I doubt it's it, but I just wanted to throw it out there.
