For the sake of fairness I'm not comparing the song to actual band music, but the use of rock by other kpop acts. GBGB is a kind of pop-hiphop mix that is very typical of kpop boy groups, with some faint guitars added to the instrumental. That barely qualifies as rock inspired, even in the context of kpop. Many kpop acts have done songs with a lot heavier rock influences. Girl groups, boy groups, groups from their own generation.
Yet their company promotes TXT as some trendsetters who brought rock to kpop. The song or the group are not my problem; you can like TXT, you can like GBGB, but I find this kind of mediaplay a tiny bit laughable.
