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 at least 2 out of the following four:

-have at least 1-2 genuine bangers

-have a fresh vibe or unique sound

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

-have quality original scores

The top five dramas must have 3 out of 4.

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

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 always have a pretty good sound track
