Favourite Opening Themes?

[Naiwen]

I personally prefer the opening song of "Tales of Graces", in Japanese, which I have in the background at all times. How about you? What are your favourite opening themes according to you?

My favorite opening theme from any game would definitely have to be Halo 3. The nostalgia when you hear that opening theme on that game is just amazing and it gives you goosebumps hearing it. When I hear it, it brings back a lot of memories of when I used to play it a lot with a group of friends I knew on Xbox.
