Hey guys... So I'm a bit obsessed with the Nevermore house. It's the perfect concept, perfect execution, perfectly done overall.
The only reason I created this account was because I noticed some information was sadly missing from this thread. And in my obsession with the house, my research brought me to an answer that I felt I *needed* to share with all of you.
Brian Tyler's score for "Frailty" is used for the entrance to the Nevermore house; I believe it's the main title, but I could be mistaken. While I haven't found any YouTube clips of the music, the score is available to download from iTunes, Amazon, and the like.
Hope I was able to shed some light!
