I more or less agree with all of that. Like if I'm working (or doing anything, really) and I have YouTube build me a playlist, I skip things like Polyphia in favor of driving electronic dance and/or pop. Conversely, I'll sit down with my guitar and try to transcribe Polyphia (two entire dollars for the tabs?! what am I, desperate?!) in the hopes of developing my chops, or expanding my personal little chord library, working on hybrid plucking, whatever. Very different headspace vs. casual listening, absolutely.
I'd only argue that I could pick out something like a melody in that track, but I think it's a little subjective, especially before it gets to the second half of the song when the whistle-like melody shows up. But yeah, even then, it's kinda like the melody from hell. Which is fine. Appropriate, even.
But omg a live show. Fucking Chromeo, for example, spun a set for their show instead of playing the instruments that I know they can, and as featured in their music videos. Was lame-o. Danced instead of watching, but I can dance anywhere, guys. No idea why people wanted to crowd the stage. To see some buttons get pushed?
