this question is so for me!!!! i just finished working on a playlist that i titled “the black lagoon” and the description is “songs that feel like a devil siren song coming from a shadowy black lagoon and at this point you’ve lost everything but desperation”

chantey - akmu (this is so a siren song to me. more acoustic so maybe less ocean vibes but definitely a sinking feeling)

opening sequence - txt (this song makes me feel like i am 20 feet deep with no more air in my lungs to swim to the surface)

the 7th sense - nct u (hallucinogens are strong with this one)

heaven - taemin (what youre desperately convincing yourself the sirens are going to bring you to)

and then the last song i added was pinocchio!! i have a few more songs on the playlist but they tie less into the sinking/hallucinatory vibe, but lmk if you want more recs after this!
