The guitar is supposed to be the lead/primary voice, however I can see your point. Do you mean the low piano voice for the “dwang part”? How are you listening to it? Personally I float between the layers after the first loop. Also did you see/hear yesterday's one?
a song, is basically ONE PRINCIPAL PROTAGONIST and rest is to "support it/green leaf it". Like a story.
-and/or i remember the trope, where a singing group is criticized and MC say : you guys keep trying to fight to become the protagonist and why its bad.
Its kinda same thing. I have no clue what to listen to.
