Say what you will, but "Another One Bites the Dust" (a John Deacon composition) is still a very important song. It provided the basis for the breakout single by that misunderstood genious, Weird Al Yankovick. Weird Al's "Another One Rides the Bus," and the flip side, "Gotta Boogie" ("Gotta Boogie..... Gotta Boogie.... Gotta Boogie.... I gotta boogie on my finger and I can't shake it off!) began his meteoric rise to susper-stardom.

And I'm NOT bandying about the word "genious" here, either!
Don't forget the David Bowie/Queen composition "Under Pressure" launched Vanilla Ice's career too when he ripped off the main bass lick (they later sued and got a nice settlement) for "IceIceBaby". I file that under 'bad Queen accomplishments'.
