Man, Hansione, I think you nailed it with Meatloaf’s I Would Do Anything For Love (But I Won’t Do That). If memory serves correct I believe the thing Mr. Loaf wouldn’t do for love is find another chord (it repeats the title chorus, what, six or seven-hundred times?).
Other songs that make my flesh crawl:
Every Rose Has A Thorn – Poision (the worst of a bad genre; the heavy metal ballad)
Let’s Hear It For The Boy – by God knows who from some 80’s flick
Anything with excessive vocal histrionics ala Whitney Houston or Christina Aguilera (who just bugs me anyway)
NSync/Backstreet Boys/98 Degrees etc. – I honestly honestly honestly could not tell you the difference between any of them musically (or pretty much any other way for that matter).
Sometimes When We Touch – Dan Hill (possibly the "Plan 9 From Outer Space" of lite rock ballads)
I’d go on, but I’ve only got a 2 gig hard drive.
