How wonderful! I had no idea there were albums connected with the dramas. Is that common and is there a search term that’s right to use?
Yes you can find a number of the “original sound tracks” on YouTube. Just search the drama name and sound track or something like that on YouTube. Two good soundtracks on Youtube are for Goblin and Legend of the Blue Sea. Some of these dramas put a lot of effort and money into the music, and there are big-name artists performing them. Here’s a recording of one of the theme songs to Goblin from Punch, for example, https://www.yesasia.com/us/korean-music-soundtrack/0-0-95-bpt.46-en/list.html. And here is “Beautiful Life.” https://www.youtube.com/watch?v=W0cs6ciCt_k
A lot of the dramas come out with their own CD OST albums and related promotional material. You can find a lot of these on YesAsia.com. Go to the site then to Korea, then to music, then to soundrack/OSTs. It’s a little hard to navigate at first, but here’s a direct link: https://www.yesasia.com/us/korean-music-soundtrack/0-0-95-bpt.46-en/list.html
This is a large and legit company which sells legal merchandise, not bootlegs. The only difficult thing is shipping costs have gone through the roof, they mainly ship from Hong Kong / Shenzen, but because of all the trade tensions I think they have to route their shipments through Europe by DHX (they used to use ChinaPost). Shipping used to be something like $7-9, but I think the last one I paid was something like $27, so it is becoming cost prohibitive for some people is my guess.
