I voted for Midna's Desperate Hour, and I'm not surprised that it's winning. It's beautiful. I play that song on piano too. It was the first Zelda song I learned. ^^
Midna's Desperate Hour for sure. It had that, "RUN AS FAST AS YOU CAN TO HYRULE CASTLE MIDNA IS DYING" feel to it. It sucks we only got to hear it for about 10 minutes
