What about their fifth album, A Day At The Races? It's a terrific album if you ask me - I'd say their best period was their first five albums! To me it was News Of The World that began their mediocre period, which ended when they redeemed themselves with a good album called The Works.
A Day At The Races is a good album yes, and so was News Of The World, I rate them both highly, but not quite as high as their first four, more experimental ones. For me, the mediocre period started after News Of The World, with Jazz, and I wasn't impressed with any of their albums after that until A Kind Of Magic which showed some sort of return to form. I especially disliked Flash Gordon, The Works, The Game and the awful Hot Space.(Only one decent track on that - Cool Cat). To me, by then, Queen were just another rock band without much creativity or invention. Funny how the singles of theirs that I disliked the most tend to be the ones played the most now. I think Another One Bites The Dust is the worst single they ever released, didn't like Under Pressure much either, and certainly wasn't a fan of Crazy Little Thing Called Love. Different fans like different things obviously, but for me, they never recaptured the magic of those first four albums. (Though I must say, of all the albums they released after News Of The World, easily the best one, for me, is Innuendo) I only possess the first six on CD, though I may at some point buy Innuendo.
