Breathe in the air
Loved the usage of Pink Floyds "Breathe" from the Album Dark Side of the Moon.
For those who might be unfamiliar with the connection, it was a long standing theory that if you started the album at the right MGM roar of the movie, the albums music & lyrics would "sync" with the action and visual themes of the film.

So to see this song included makes a nice allusion to this long standing theory and honestly the thematic connections to Oz fit quite fluidly IMHO.
