That's cute.
So, I saw it mentioned last week that Blackpink only won because TT wasn't eligible anymore. Why is that?
I was only half-kidding. Kii.
Basically, in most Korean weekly music shows, a song is only allowed to win a maximum of three times. So because Twice already won 3 times for their song
TT, they can no longer win for it. Winning thrice on a music show for the same song, or what we call Triple Crown, is an extremely rare instance so it is rather special to achieve such success.
Music Bank, I believe, is the only weekly music show where an artist could win multiple times with one song. That is why Twice is still winning there. They just won their fifth straight trophy this week.
