What's everyone's favorite anime openings and endings? Try to limit to five a piece.

My favorite opening is probably obvious :rolleyes2 it's "I Am A Pioneer" from Tenchi Muyo. In a distant second would probably be "Biggest Dreamer" from Digimon Tamers.

My favorite endings are prabably either "Happy People" from Bleach or "Viva Rock" from Naruto.
