Two favourites from two eras of Iron Maiden for the commute today: Iron Maiden (1980) and Piece of Mind (1983).
Iron Maiden (1980)
Piece of Mind (1983)

Also noted for having within its ranks former Maiden drummer/masked gimp Thunderstick, who appears in the video below... playing the roadie (his brother portrays the drummer in the film). From the embarrassingly horrible Julien Temple film, Biceps of Steel (1980):
Head On (1980)
