I prefer the label "stadium rock" for their 80's work--but yes, they do become more danceable. At any rate, it's greatly underrated by critics.

On the worst: I'm going to have to go with the Saturday Night fever soundtrack. Everything I resent about "Dust in the Wind" is even worse, in terms of the popular being the enemy of the great.

There are no Canterbury artists until 211 (ex Soft Machine guitarist Daevid Allen), and there are fewer prog albums, as it gets nudged out of the way by punk from one side and synth pop (e.g. Ultravox, whom I like) from the other (I don't think disco competes with progressive music), so that prog SEEMS outdated (and some of it certainly is), when in reality there are excellent and diverse works in that genre through the 80's. Again, this for me exemplifies the popular edging out the great.

The album that moves me the most from the top 10 (I'm a late comer to Marquee Moon and still haven't heard Animals or a few others) is Aja, but the most moving song is Bowie's "Heroes" with Fripp's wonderful guitar riff.
