It's kind of funny, like when your recording the song do you just walk in the recording booth and then walk out? You guys know the papers with the lyrics on it that idols use when recording songs right? So like imagine your an idol and you look at your name and your lines and all you get to sing is "Bureul jipyeora" or your whole career you only sing for 24 seconds. Why even be an idol if people dont even remember you because you barely ever sing and on top of that your in a group of like 8 other people and you barely get paid because the money has to go through 7 other people now that's robbery at its finest.
The worst is when a member of the group produced the songs and that one member of the group keeps getting no lines over and over again. And you cant say "She/He doesn't speak korean" or "They aren't the best singer" first of all the Korean thing could get by if they just debuted but not if they're a 5 year old group already and why would the company debut them if they cant sing? The shade is real.
