WCD is an odd one for me, it has a special connotation because it was the album really got me into Genesis, and one of the earliest albums I listened to obsessively, age 10-11. I think it has good depth and range, but there's also a maturity about it that makes it a little boring or something. The sound is unadventurous, which may be a production issue. I return to it infrequently but when I do, I enjoy the heights very much - NSOM, Jesus, driving the last spike and dreaming while you sleep are all great but countered by very mechanicsy MOR fare like Never a Time, and I was never a big fan of Fading Lights.
I am glad to see it top of someone's pile though!
