Favorite anime opening?

[gwolf666]

I think all of us who watch anime have a favorite opening, or several. It's impossible not to like any of the songs, right? Of all the anime you've seen so far, which is your favorite opening? Or if there are several, which are your favorites?

For me it would be Blue Bird by Ikimino Gakari from naruto. The melody is just wonderful. Whenever i hear it, it gives me so many fun memories.
