"More Than Words" shouldn't even be in the same sentence as "worst song." It's actually about something, was composed by someone with actual knowledge of music, and wasn't overproduced to death like everything Winger ever made.
Really, even if you hate love songs, and/or hair ballads,* go back and listen to some of the other hair ballads that were put out at the time. I guarantee you every one of them was worse. Every Bon Jovi hair ballad was worse.** Every Cinderella hair ballad was worse. Every song on
this list was worse, and I don't even hate "Home Sweet Home" or "I Remember You."
*And I don't even consider "More Than Words" a hair ballad. It's too good for that title.
**For that matter, every Bon Jovi
song was worse.
