I've been really liking GFriend's Apple because while it is sexy and sleek, it has some undercurrents of something eerie, sinister, or otherworldly going on... I can't explain it but I feel like something bad is about to happen?? but I love it and I can't stop listening to it.
Another example would be Red Velvet's Ice Cream Cake, it just sounds wrong in the best way (this is a compliment). The "la la la la la" parts specifically in the prechorus is so unnerving although I don't know why.
An incorrect example would be Irene and Seulgi's Monster. It does have a monster/horror concept, but it's not unnerving/eerie imo.
Any recommendations (bg, gg, or solo) would be appreciated! Thanks :)
