I have thought this thread is going to be about some professional constructive criticism for rapping. But straight up bashing lol! The guy you have brought is not even a kpop idol. Idk where did you find him lol. What did he even do to you? Did he threaten you top listen his rappng or what? lol. He has made no harm to you. You have listened him yourself! Okay his rapping is unlistenable that's it. No need to create 7 pages thread or bashing him!
There are great idol rappers as well as bad ones. Not everyone is extremely talented. But they still try their best and they work hard. But there are lots of extremely talented people but chose easier way to get fame! Can you just try to see the bright side? I like kpop songs with rap parts that's why I listen YG artists, BTS & SKZ etc. I like some NCT, Red Velvet songs. It is true that rap parts ruin the song. But it's not that unlistenable as the guy you have brought here.
How you still have the face to act all high and mighty after making fun of an african american female rapper incorporating sexuality in her rap and even added a race dimension to it, i'll never know. teach me sensei.
