Dramas with great OSTs

Only dramas with great OSTs in this list. They are in order of which I think has the best.

Requirements for being a great OST must have :

-have at least 1-2 genuine bangers

and/or

-have a fresh vibe or unique sound

-have songs that fit the mood or help tell the story perfectly

FANGS of FORTUNE has hands down the greatest OST and is a cut above the rest in every way - bangers, unique sound and tell the story.

Revenge Love OST is exceptional in how well the songs create its angsty vibe and fit the mood and tell the story.

***There seems to be a trend that BL's tend to have always have a pretty good sound track
