Oh jeez, I wish I'd seen this in April! I'd been wondering the same thing ever since I read the book -- as soon as I develop an obsession for something, music begins to remind me of it and I can't help but form my own little playlist. But JS&MN has been thwarting me for years; something about it is so difficult to capture in music.
I've also been (slowly) putting together a FST totally independently and hope to finish it by the end of the month. Go figure. But I think the more people involved, the better range we'll have. The search should continue.
