@Legendary Pink Milk I like the example you made, but some things you mentioned I don't think are necessary, and I don't think the OST info should be on the drama's main page like you have made in your example. I think it should just be a new tab added to the top of the page with the Episode guide, Reviews, Stats, etc. I don't think the main page needs to be any longer than it already is.
Agreed, I think an extra tab would be fine - OST info isn't something everyone wants to see right off the bat, unlike actors and reviews; after all, although not a never, I think it's rare for people to watch a drama or film just because of someone on the OST credits unless they're a really big name, so this would be more relevant for people who have already watched the show, or who are looking at an artist's profile to see which songs/OSTs they're credited on, people who are specifically looking for the music. Maybe MVs could be embedded in secondary playlist under the trailer button though.
For the soundtrack listing I think just a simple album track list, linking the titles to an official MV/audio release, maybe on youtube or spotify, and linking the artists to their mdl page should be fine. Of course, it'd be nice to see the album art too, maybe as a pop-up photo album though if you want to include the covers of all the singles.
