I grew up with this song and so I watched it, a cover of the song nonetheless, and I was enthralled.
JTBC Superband is a new reality show in South Korea where they have contestants team up in bands to perform.
I have not seen much, and they have not subtitled the episodes and it will take me a really long time to figure out the conversations. So I haven't watched it yet.
But here are the YouTube versions: take a listen and tell me their talents are not insanely good.
Most of them are Korean Americans, but I still have problems with their pronunciations, here and there.
But their voices, and music prowess, they are so good.
