Tolvo, first off I also don't think the building was intended for Seath originally. Or if it was then it was for more than just Seath. You've answered your own biggest question actually in this thread. Why music? The only place with confirmed working music is the lab. I see the stands you're taking about etc but they're also commonly used to read or lecture (maybe channel from?). Music is a powerful way to condition someone. Makes sense for an experimenter to have it around. Not only the creepy punishment music but maybe he had nice stuff for rewards.
There's also the possibility that the building was made entirely with Seath in mind. What does he need? A room at the top to hang out and receive channeled information. A laboratory. Check and check. A home? He had a nice cave. So why the rest of the building? Would Seath be a popular choice for Duke.....I doubt it. Place a normal building in front of his real home. Nice start to camouflage. Then add a fairly normal human sized library. Suddenly it doesn't look like a dragon is the duke at all. Add a figurehead Duke and the masses love it. If Smough was kept away from knighthood because of his actions it stands to reason Seath would have had to be on the down low too.
So who would make a good figurehead Duke? I would pick someone wise, and adventurous. A real world ruler kind of guy. Someone you could trust around a crystal too....
