I see kpop fans don't consider sm groups as real artists because they don't produce their music. Even though the groups have the best vocalists and some of the best dancers but it seems that still is not enough for kpop fans do respect them as artists. So why do you think sm doesn't let them produce and get more respect?
also, do you think vocals and dancing aren't real talents? Why are they considered lower than producing? It's not like most kpop idols produce on their own anyway, so how is writing two lines in a song produced by a dozen producers more respectable a talent than a proficient vocalist?
