I'm responding by showering you (undeservedly) with more drops of expertise, so not only will you bestow upon me your respect, but maybe you'll even make me a bank transfer. Pop metal won't mean anything to you. However, many of us around the world use this term to encompass that branch of music which is essentially pop (in the sense of having wide accessibility, usually through "hooks" that are melodic, rhythmic, or perhaps in the lyrics, etc.) and characterized by distorted guitars, piercing vocals, explosive drumming, and so onāessentially all the outward trappings of metal.
"Here Comes the Sun" by Harrison and "Paranoid" by the Sabbath are both pop songs; in particular, the former is country pop, vaguely inspired by what the Byrds, Flying Burrito Brothers, etc. were doing in California, while the latter is indeed pop metal, a simple and irresistible litanies from Ozzy (about a romantic breakup) over Iommi's great insight to darken and blacken as much as possible the hard rock form invented by Cream, Hendrix, Zeppelin, Beck, Kinks, or anyone you like.
The Ten are pop metal: saccharine, often ridiculous, sometimes featuring brilliant melodies from their crooner Gary Hughes. Saigon Kick are pop metal, and so are King's X if you want. Hair Metal is all that AOR or Hard Rock or pop metal or FM rock (???... This definition of yours is even more all-encompassing than pop metal) highlighted by curly heads, perms, hairy chests, grimaces, extremely vulgar macho attitudes, which was in fashion during those years Iāve already mentioned. So Poison, Whitesnake, Stryper, Motley Crue, Guns & Roses, House of Lords, Cinderella... all exceptionally varied people if youāre passionate about the genre.
As for the Beatles, I'm glad you have no issues with them: so itās just the two of us who donāt. When you manage to write (assuming you write what you think, of course... if you're just messing around, then never mind) about them not in terms of "macrocosmic ineptitude," but in terms of "I don't find anything noteworthy in their melodies, in their arrangement experiments with their producer, in their voices, in the fact that people still talk about them as if it were yesterday, in the strangeness that they've managed to unite in praise jazz musicians, classical musicians, metalheads..." then you'll be a gentleman like me.
At over forty years old, and now that you think about it.
