Evidence that clearly shows Rhyu Si-min's resentment

I didn't realize it was Jang In-su's channel because I heard Rhyu Si-min was appearing again, so I checked it out right before starting.
There was a link to some Black female artist's music there, and the song was "Bust Your Window."
After looking into the background, I saw that haters were leaving that song in the YouTube comments everywhere, claiming Rhyu Si-min picked it as his "professional pick."
But the lyrics of that song are something like, "A woman who was dumped by a man says, even if I smash your car window, my anger won't subside"...
How much must he be seething that he personally selected a song with those lyrics to put on Jang In-su's broadcast, basically saying, "Understand how I feel, damn it"...
It's so incredibly childish, you jerk...
