Yeah your first sentence there is basically what I meant, although by it becoming the main focus I think there's a chance people are instantly turned off and might end up missing the actual point. I'm not sure about the no substance thing - I mean, what constitutes a pop-rock song being substantial?
With Everything Now I do agree in the sense that it's talking about big ideas without actually saying anything about those things, but it still works for me because I get a sense of sadness/unease/anxiety from the vocal delivery which plays well off of the saccharine sound and production. It's a soundtrack to an idea rather than an interesting expression of an idea.
I can see why people find Creature Comfort cringeworthy or obnoxious, but I think there's more depth to it than anything on Reflektor. The second and final verses seem self-critical in a way they never have before.
