There could be copyright issues if they are uploaded. We need at least a section with the names of the songs. And maybe embed the OFFICAL youtube songs.
Update: About what Skye has written, "Next to a song title could perhaps be an episode number and time stamp or short description of the scene it's played during."
The would really be hard to pinpoint and would not be necessary. Some songs from an OST are not even played in the drama at all and are just in the OST album. Also, if the song has been played more than 20 times, it would be a bother to keep a record of when each song was played and in which episode at which duration. People will have to keep checking the OST instead of enjoying the drama/movie and it will make them feel like a chore and no one would do it (just like episodes summary, which is rarely added). Moreover, it is not even important info to know and would contain spoilers if we add a short description of the scene.
What we need is something simple like this: http://wiki.d-addicts.com/Signal_OST#Signal_OST
And maybe the ability to embed or link to the ***official**** YouTube song, which would be a big plus since lots of people sometimes have a hard time finding the official songs.
Also, we could do iTunes and YesAsia affiliate links for people who want to buy the OST album.
