We Built this City is easily the worst song of all time... It makes Achy Breaky Heart bearable by comparison.
Nostalgia points refuse to let me put Starship in the dumpster, even though they themselves have done so.
I used to hate "Nothing's Gonna Stop Us Now" but then I watched "The Skeleton Twins" in what may be my favorite movie scene of all time, which was set to that song, so now I love it.
This is my vote for worst song ever. I honestly went out of my way to turn off the radio or leave the room whenever it came on.
