No love for the LoZ series? Some of the most easilly recogniseable and epic tracks around. My personal favorite is the Wind Waker; there's not a single melody in that game that I don't know by heart. Just makes the game so much fun to play. TP was good, too, but had an overall less optimistic tone.
I also have a soft-spot for the older Castlevania themes. "Vampire Killer" or "Bloody Tears" were both amazing. They really knew how to get the most out of the NES!
