Since I started listening to jpop last year I tried to keep track of jdrama ost. I made a list ffor myself and decided to share it here (and added some music videos as well). It's not 100% complete tho, but most of this can be found on streaming sites anyway.
If one of those 'vote for best jdrama ost' rolls around at the end of the year, y'all can use this as reference.

Oh, I've just seen your posts. Thanks a lot, that wil be so helpful !!! For any best Ost of the year or whenever we need references for those dramas. 

I wish we could add OSTs on the drama pages, because sometimes I have difficulties to find them. 

Once again, thanks a lot !!!

Skipped my non Japanese songs as they are not apropo for this thread (MG2018 and Reborn)

--Still editing --

where can i download them? is there a website?

 lighttomydark:

where can i download them? is there a website?


one place I know of for downloading is jpopsuki, but I dont know if it's still around, I'm not a member there.

most of the links in this thread are dead because the websites were shut down but maybe since then these songs were uploaded on youtube.

if I'm bored at work sometime perhaps I'll update this thread.
