Guys just enough....
Chanyeol may not seem great but he is good on his own. Him being on the show was actually good idea. it shows that he is trying to became a great rapper and he'll learn from it. There is a lot of great rappers in there , they'll help in some way.
Plus he wasn't screaming the whole performance. His voice is deep and if he rapped the way you guys want it for the whole performance. The audience screaming would have made it hard for us to even hear him rap lol. After all he was being too hyper , excited and also he is doing what he is told to do. he wasn't trying too hard to be an underground rapper , he is naturally like that.
