- "Baby, you're a rich man; baby, you're a rich man..." Especially notable since it is almost unheard of for Apple Records to allow an original Beatles recording to appear in a non-Beatles film (barring of course a few other exceptions).
- Trent Reznor and Atticus Ross's Oscar-winning score, especially "Intriguing Possibilities" and Mark's Leitmotif "Hand Covers Bruise." And then there's that chilling industrial cover of Grieg's "In the Hall of the Mountain King."
- Scala's haunting cover of Radiohead's "Creep" that plays during one of the trailers. It's heartbreaking, it's haunting, and it's beautiful. Many people consider it the Trope Codifier of the Moody Trailer Cover Song.
