Yeah "Hot Space" is a good call for terrible albums. I have Hot Space becuase i too am a Queen comletist.

Other bad albums that i own becuase i "collect" certain bands include:
George Harrison - Dark Horse
Paul McCartney - Driving Rain
Van Halen - III
David Bowie - Buddha Of Suburbia
Elton John - Victim Of Love
Rolling Stones - Dirty Work
Aerosmith - Rock In A Hard Place
Led Zeppelin - Prescence (i know a lot would disagree with me on that)
They are a few off the top of my head, all rock comletists have to endure duds like the above taking up precious room. Lol.
