Dedicated to those who don't have a clue how to grind an axe!
1) "I Love Rock ‘N’ Roll"—JOAN JETT & THE BLACKHEARTS (1982) Not sure who the guitar player is here (I don’t think it’s Joan), but it sounds like he/she played it in his/her sleep!
2) "I Love It Loud"—KISS (1982) It’s a mystery who actually played this stillborn thing (it's most definitely NOT Ace Frehley) because the lead guitarist position for Kiss was in flux at the time, but whoever it was, it sucked like a Hoover vacuum...
3) "Mad About You"—BELINDA CARLISLE (1986) Duran Duran’s Andy Taylor ruined a perfectly good love song with his squealy solo that sounded so out-of-place with the rest of the tune—hey Andy, come back when you learn how to play that thing, okay, Bud?!? Good rule of thumb: guitar feedback and love songs generally are not a good mix! The Carpenters had a song called "Goodbye To Love" that suffered from a similar malady.
4) "Hot Blooded"—FOREIGNER (1978) Mick Jones sounded like he was playing with an ice pick here instead of a guitar pick...
5) "Hot Girls In Love"—LOVERBOY (1983) With all apologies to Loverboy's Paul Dean, I’m not sure why this one bugs me—it just does. Dumb song and even dumber video too...
DISHONORABLE MENTION: "Cover Of The Rolling Stone"—DR. HOOK & THE MEDICINE SHOW (1973) This would have made the above list, except for one little thing—it was supposed to sound bad!
