Whats your favorite Anime Song???

Life is like a boat - Bleach
My favorite song is the first opening song of Code Geass..I believe it's called Colors..? There are a lot more I like..But, this was the first Japanese/Anime song I kept replaying, & I still LOVE it!
Hands down Fooly Cooly, the Pillows did a fantastic job!

Also liked the Non Non Biyori soundtrack a lot, since it fit the mood of the show so well.
