So we've argued single favourite movie to hell and back. Let's widen it. Name your single favourite piece of music of all time?
Difficulty: if it's an album, name the track; if it's something like a symphony, name the movement.
Nine Inch Nails, Just Like You Imagined from The Fragile.
Album version (relatively low quality - you can get 96/24 FLAC from the NiN store). A live version with a super-amazing guest pianist Mike Garson.
