which one is the most "non-friendly" music released by SM girlgroup ?

Red Light.

Quote from SooYoung

i would say Red light

ZZB, NL and IGAB all have a more original construction than Red light

but in contrary of all these songs RL doesn't have the easy chorus to sing along who get stuck in your head

Tbh for me Red Light was ahead of its time. Most of the ggs or even bgs release this type of song in this gen.

Kyeojyeosseo red light
Seonmyeonghan red light
Seuseuro kyeojyeo geugeoseun red light

red light is such a bop i will cry T_T

Next Level is not very experimental in my opinion. It's definitely experimental in SM standards because Next Level rap and instrument parts are very catchy. The music part playing in Portal is very detached, but Sm added sauce to the song in that part.

When I first heard SNSD's IGAB song, I was very confused why it was constantly jumping from one track to the next, but then it became my favourite SNSD song.

To me between Red Light and Zimzalabim. But I think I started to like Zimzalabim much later. After the live concert performance, I started to like the song completely. Red Lights instrument parts, harmony and bridge parts are very good. I'm a Reveluv but I warmed to the chorus in Zimzalabim much later.

Red Light. It's too dark for gp.
