Most popular music songs, even rock/metal/prog, no matter how niche, long and/or virtuosic they are, are built from sections that repeat and contrast for audience impact. This is rooted in the kind of nigger+white frankenstein pop music that came out of America in the 19th century. Classical works rely on continuous motivic development and long-range harmonic planning. I guess it's just a tradition most popular genres neither train for nor reward.
You can find literal fucking punk rock with "classical scales" (lmao). That doesn't make it classical.
