TWO SORTA RECENT VIDEO GAME ad campaigns juxtaposed tableaux of in-game combat with music of stunning emotion. If you'll permit a pair of YouTube links, these are worth sharing.
Gears of War, featuring the Michael Andres/Gary Jules cover of Tears for Fears's "Mad World"
Halo 3, featuring Chopin's "Raindrop" Prelude in D flat major (direct link if the video's a bit jerky):
Perhaps I'm an old softie, or a sucker either for sad piano music or Tears for Fears, but both of these choke me up a little.
