I liked when he talked about putting lots of short tracks on albums to get around the choir usage rights. If you didn't watch the whole thing - a 2:30 track with 30 seconds of choir still counts as 2:30 worth of choir on the album. But isolate the choir bit in its own track and it only counts as 30 seconds. That explains why things like the Horton Hears A Who main titles are split into three tracks. Clever.
