Favorite Korean Drama OST?

I don't think I have a favorite drama OST, but I have a lot of favorite songs from dramas:

Tamra, The Island: Your Tears (Main Theme)♥, Jane Park - 이어사나 and 미카 - Blue (Love Theme)♥

Gumiho: Tale of The Fox's Child: 상사 (모래)♥ and Opening Title

White Christmas: Opening Title♥

City Hunter: Oh Jun Sung - City Hunter (instrumental)

Cruel City: Jo Jung Hee (조정희) - Everyday

The Princess Man: Finally (instrumental)♥ and Destino

The Devil: Opening Title♥

Ghost: Block B - Burn Out

Iljimae:Park Hyo Shin (박효신) - 화신

Goong: Opening Title and Frozen Pond♥

Hahaha might continue my list later. xD

All of Coffee Prince's OST songs
Cinderellas's Sister Yesung - It has to be you
Secret Garden Baek Ji Young - That woman
Gu Family Book 4men - Only You
You are Beautiful Jang Geun Suk - Without words
Arang and the Magistrate K.Will - 사랑은 그대다
Boys over Flowers Jisun - What should I do
Heartstrings Yonghwa - Because I miss you
Cruel City 김용진 (보헤미안) [Kim Yong Jin of Bohemian]- Hurt

Secret love: incurable disease Cheongdamdong alice: daddy long legs Dream high: all the songs

The Moon That Embraces the Sun Boys Over Flowers Cheongdamdong Alice Goddess of Marriage Dream High Heading to the Ground That Winter That Wind Blows

City Hunter 1 Litre of Tears A Love To Kill My Girl Love Rain Lie to Me Two Weeks Delightful Girl, Choon Hyang Coffee Prince Boys Before Flowers

for me it would be: secret garden ost (Liar by Oska is love and also that man by Hyun bin) innocent man ost (love is like snow) fugitive plan b ost (fav song from there would be Mayday)

For me it is Bridal Mask/Gaksital and Secret (2013). They have the best OST songs and V.A.

But all music dramas has good OST songs too, but I think those are the best. :)
