Yeah, I'd thought Wilson would be in too, if only for the reason that a lot of people seem to figure that if they like the band so much, they must like the vocals too. I'm sure Geddy was on numerous lists. Maybe some people really do love his voice, but I have to wonder if Geddy sung over the music of a reasonably similar band they didn't like whether it would really improve their opinion of that band much.
Similar thing with Haken and Jennings. I used to be a lot more into them (even have a hoodie I still wear occasionally after having seen them live), but his voice is part of why I just don't listen to them nearly as much as I used to.
DTF does seem to have slid towards metal over time, but that almost seems true in the prog world at large. Many more bands getting heavier, downtuned or extended range guitars, double bass, sometimes growls, even some softer bands have beefed up their production over the years. And this is reflected in forum tastes, prog rock-only fans seem more of a minority now than they were in the 00s from my recollection.
