I guess you dind't read it through, i want to ban a SONG not a USER
Which is also impossible. I mean if you allow to play YouTube links for everybody. Then everybody can upload a song and play it. You can't check for a name. Maybe you could rely on the YouTube song/music recognition, but that's all.
Otherwise if you just want to stop a song from being played that is uploaded, then it could work, but only with workarounds.
(Like the song would start, because the bot command would trigger first, then the script would stop the song again and kick/ban the user)
