My current favorite is Fire of the Heart Singer by Julia Peng ft. F.I.R.  from The Journey of Flower OST.
For me the best Chinese Ost Song I've ever heard is Huo Wallace and Yang Zi's song " I'll remember you" because it's both calm and beautiful, totally my type of music <3

Yi Ren Ru Meng by Huo Zun from Legend of Mi Yue's OST, simply breathtaking <3

Would anyone happen to know the opening song for 'The Imperial Doctress' drama?
Only chinese drama I watched. Love me If you dare. It has great ost.
Don't know about the best but these days I can't stop listening to this song~ Do check the drama!


Back To 20 - Our Tomorow <3
Easy Fortune Happy Life OST <3

This is the best OST for me!! from In Time With You! <333 

Still - Weibird Wei

韋禮安 - 還是會
Bromance OST is <3

Notable songs in Bromance:
Unstoppable 3 (Ian Chen, Andrew Tan, Bii, Dino Lee) - Epochal Times
Bii - Back in Time

I really liked the music from 'Just You' and 'Fall in Love With Me' Taiwanese dramas. (Sorry most of them Aaron Yan, I am a big fan of his music with Fahrenheit and especially solo.)

Top 5 Favorite's (in no order):

Aaron Yan: Unstoppable Sun
Freya Lim: Unfinished Story
Alien Huang: Point One Percent 
Aaron Yan: Taipei Dreamin'
Aaron Yan: That's Not Me

Also from the drama Substitute Princess, I love this song from S.H.E : Innocent Woman
My favorite Chinese ost would be from the drama Autumn's Concerto. It is literally one of the best and catchy osts I've heard

Autumn Concerto has some of the best OSTs. Della Ting's I love him and Ping Guan's I thought. I also love the osts of Fifteen Years Waiting for Migratory Bird. 

Fire of the Heart - The Journey of Flower

Let it die - Proud of Love

You are Beautiful - Cambrian Period

Season of Rain - Moon Lovers

Love In The Forlorn City

Very beautiful, melancholic OST song:

"There Is A Love Called Letting Go"

Watch it at the very beginning of the ep,  its amazing lyrics and intro montage hooked me into the drama right away:
