Missing Track(s) in Spiral Knight OST?

So yeah, I usually get attached to the music of the games I play, and Spiral Knights is no different. SO, I was thinking of getting the OST, however, I noticed that the OST is missing the new Shadow Lair music. Am I not looking at the right OSTs, or will they not be added? I'd hate to buy an incomplete OST, then they update it afterwards and I get screwed. If they won't add them, is it "possible" to somehow find the sound file for those missing tracks?
tldr; I played the Shadow Lair for the first time last month, and I want that track when you and your team is running through the Unknown Passage. So awesome. D:
Edit: Nevermind the part about finding the sound files for the game, found them just now. But still curious if they're gonna make a legit version.

As far as the shadow lair music goes, the OST was released before SLs existed, so naturally they wont be there.
If you really want certain music, they exist as separate files withing the games folder...

The soundtrack you can buy for real money doesn't have IMF theme too. I think they should do volume 2 or sth like that

Markosmesh, obviously I know that. Both bits of information that the Shadow Lairs were released afterwards and the sounds files being there, as I mentioned in my first post.
And yeah, I was thinking they'd make a Vol 2 or something, but I think they'd need more tracks to d that. Maybe there'll be more cool music with the missions update. :0

now that ... i like the sound of , mission music , one for each monster/status theme

Tracks are not missing they were simply added after we made the first soundtrack. Once we have enough new tracks for a second volume, we can release another if there is enough interest.

Ever consider releasing an OSV, or unused tracks to spice up volume 2?

well thas a relief, looking forward to new spiral knights soundtracks :)
finally someone else who realizes it... or just bought the ost , YES that music is missing, but so are the winter haven, and lockdown themes (lobby and in game) i thought there was yet another missing track but it doesnt come to mind now, but i have never heard the shadow lair music, ill have to check that out
