Not really that true. I mean, it's not 5-riffs-a-minute like some metal can be, but a lot of the classic bands had a higher density of ideas than stuff like in that Pylon song above or a lot of The Fall's stuff or whatever else.
Genesis has individual songs that I think are great, but I think there's too much balladry and whatnot trying to enjoy any of their albums on the whole. Which isn't to say soft = bad, King Crimson has some amazing more mellow or folky stuff, VDGG touched on a kind of minimal/ambient prog at points that was really unique, I love classic Yes, but Genesis kinda drops the explicit progishness. Like, I almost think it's silly that bands like Marillion are considered "neo-prog" and often inherently poppier/inferior when their stuff really isn't that different from what Genesis always did. But I'll admit that they have their moments, and that I do see potential for them to grow on me (although it's been going in the opposite direction for a while).
I enjoy the Snow Goose, the others are boring af.
When I say riffs I don't necessarily mean typical rock-derived guitar riffs. I use it more as a catch-all for any repeated rhythmic and melodic unit. For my personal enjoyment, rock music must do more than simply contain riffs, it must use them as a primary way of driving the progression of the song, as opposed to (for one example) as a backdrop to support a singer. Even when judging non-metal, riffing is something I consider very important, which is why I tend to prefer funk/soul and heavier rock-based genres over other non-metal.
