There should be 161 tracks, iTunes has 160. The missing track is the last (what should be #17) on Disc 1, "From Rosy Bowers." Because of the missing track, the other tracks on Disc 1 are mislabeled--the first title in iTunes is "Music for a While" but the file is "Fantasia Upon a Ground in D Minor," and so on for the rest of the disc. I bought "From Rosy Bowers" on Amazon and imported it to iTunes but I will also have to change the titles on all of the other tracks on Disc 1. The other 5 discs appear to be correct.
