Youre right, but this isnt me reversing course, its me saying: you are using “pop music” with a different definition from the person you are responding too
Pop-music per your definition is a genre or set of genres. Pop-music per the definition presented though is any successfully commercialized music that by association with the label of that commercialized genre perpetuates further commercialization. Metallica, and thus metal that follows them falls into this category.




Fair. I personally prefer to tell people to atop being lazy.
