What are the no skip/always skip songs in your K-Pop playlists?

Hold me Tight by BTS: no skip

Most 4th Gen noisy songs that appear on my rotation: always skip. I also skip Ditto

I'm never skipping Sistar touch my body

I don't believe i've ever skipped starry night, oh!, sixth sense, i am or russian roulette.

I almost never skip BTS songs, though I do skip a few solo songs that aren't really my taste

there are so many songs...

But just going off your post, I never skip Lovesick Girl but I always skip How You Like That
