Everyone that claims that there is no artistic value in idol music is dead wrong. Although the girls don't compose the songs themselves, or make up the choreo, it doesn't mean that an idol group is of any less value than other artists. The phrase "real musician" really irks me. An idol group has another structure than bands such as Radwimps or Dir En grey, for sure. But the composers create wonderful compositions, the choreographers think of splendid dance moves, and directors create engaging MV's. And the girls, they are the performers, the faces, they are the ones that bring the whole package to its audience. And everything created in this manner is no less than a work of art. Idol groups have every right to win the award, just as other artists. This is not a biased opinion, since most of my music collection consists of extreme metal bands, which is kind of the total opposite of Nogizaka (in both music and the creative process). And that's where you are wrong, because there is nothing objective about visuals and beauty. It's all in the eye of the beholder. If you think certain members are low tier / average / whatnot, that's okay. But don't claim it as facts. Don't say that those who think otherwise are delusional. Because that is rude.
