Same name song battle: Who has the best Knock (Knock) song?

Twice

Oh My Girl

KNK

Nasty Nasty

Astro

I'm including any number of knocks for this because I happen to really like the Knock (Knock) songs, my next thread will be more picky with the titles

Let me know if I forgot any so I can add them in

TWICE and KNK have my favorite ones. KNK's debut was so good, I should check out what they've been up to since. They kind of fell off my radar.

Yeah, it's too bad. I saw quite a bit of them when they debuted but never looked into them beyond Knock which was one of my favorite bg debuts from that year. I thought they would be a lot bigger

But when I checked them out, it seems like they're still releasing music. There's always a chance they'll blow up!
