This song

has to be the worst '80s song I've ever heard.

Technically, there are worse songs out there -- almost all mainstream music made in the last two decades immediately comes to mind -- but the component elements of this song just come together in a way that is just embarrasingly, epically bad. The instrumentation is beyond godawful and the lyrics are freshly squeezed shit.

Ironically, I'd probably hate this song less if the singer herself was horrible, but she's actually pretty good, which just makes the suck surrounding her stand out that much more.
