Oh yeah, I defnitely agree that vocal work doesn't matter or else our precious Luna would've dominated the charts. Well I take back what I said if Shake that Brass was a success because I really thought it didn't do well around that time. I'm quite sure that was what was said from f(x) fans. But eh, my memory might be off. I'm surprised that she did better than Hyuna though!
It's true that more could always be done for Amber and Henry (and everyone else who is being neglected). And I am not putting aside that Amber works really hard and wants control over what she does - that's great especially under an idol company like SM which micromanages almost every single step. But I really don't think it's a great idea to talk about such issues publicly like this, I can't see anything great coming out from it so why even bother since she's still under contract with them. That's mostly what inspired my previous comment.
Don't get me wrong though, I like Amber since she managed to stay who she is in this industry - which is not an easy feat at all. She's definitely unique in the world of KPop which is why she's so precious. However, I still find her decent at best but I know talent isn't everything, there are other factors which contribute to one's success.
