Im wanting to listen to everyone favorite ost songs.

Currently I'm listening to the OST from Goblin, Shopping King Loius, and Kill Me Heal Me.

What's your favorite OST or song?

My current favorites are the OSTs from DOTS, Kill Me, Heal Me, Chicago Typewriter, Moorim School, and WFKBJ
Oh! Weightlifting Fair does have a great OST :) Thank you!!
"Glass Bridge" (from Bride of the Water God. Terrible drama, but excellent OST collection): https://www.youtube.com/watch?v=K0FOtpPqMeE

"Student X" (School 2017): https://www.youtube.com/watch?v=tldLL-SviwU

And just about any OST from Goblin or DOTS ;-)
The OST from Goblin was amazing, to be honest, it was my favorite part of the drama and one the reasons I kept watching it
@SarahEm: Stay with Me by Punch and Chanyeol is the most played OST song on my playlist! I love that song so much.
Joy: Isn't it great. I added it to my playlist recently and I can't stop listening to it. I'm almost afraid of getting sick of it.
Dramas where I enjoyed most if not all songs on the soundtrack:

Moon Lovers: Scarlet Heart Ryeo
Healer

Dramas where I have a few songs I like from the OST:

Suspicious Partner
Strong Woman Do Bong Soon
Rooftop Prince
Protect the Boss
The K2

Additional mentions: 

All the OST tracks performed by Seo In Guk or Xia Junsu are great listens for me, and although I couldn't get into Goblin personally, I agree the soundtrack is great. Beautiful by Crush is probably my favourite of that soundtrack. 
No way ( doctors)
Osts of goblin
Osts of scarlet heart ryeo
Osts of cinderella and  the four knights
two of us (we broke up)



Thank you everyone!!!! I had a long night in my house with a sick baby and we listened to a lot of OST's to pass time and calm the crying!

I'm so glad I posted this because I've added 20+ songs to my OST playlist!!
My fav OST ever is from Playful Kiss (KR), mainly "Should I Confess", by Soyou.
I really do like Playful Kiss' OST! I wasn't completely sold on the show (But boy do I love Kim Hyun Joong!!!) But it was pretty good and the music really resonated with me.
Right now my favorite OST is Another Day - N.Flying Yoo Hwe Seung (Criminal Minds OST Part.2). It's so good!!
@lwyn it is good!! I'm glad you recommended it!!!
