The first one I've been looking for FOREVER, and no one seems to know. The music in the Finding Forrester trailer, used in the second half of the trailer (particularly the part starting at "find your passion") - someone has to know this! It's driving me NUTS! And it's not Shawshank, Bicentennial Man, or Powaqqatsi, incidentally.

The other is both the pieces of music that are used in the trailer for "Thirteen Conversations about one thing," which they have on the apple.com/trailers site.
