What's your favorite anime opening/ending song?

I have too many favorites to remember them all. I'm really into Gundam 00 right now and I like most of their theme songs. There's "Daybreak's Bell" by L'Arc~en~Ciel and "Ash Like Snow" for the Season one opening. For season two, "Hakanaku mo Towa no Kanashi" by UVERworld is a good opening song. Some other favorites are the songs from the Initial D series, like "Dogfight", "Blazing Beat" and "Noizy Tribe" and the Full Metal Panic series. It'll take to long for me to name them all.

have you heard the theme song from the anime ghost int the shell stand alone complex?performed by origa the song is called inner universe and it is my favorite

Actually, I memorized a japanese song without intending to memorized it. LOL! My brother kept on playing that song over and over again. We unconsciously memorized the song. I like Mami Kawada's "Joint". It's a little alternative. The beat is very catchy I can almost hear it in my head now. _

I could say that my favorite openings are from Bleach especially opening 1 and 2,but I really don't know their name,and the 5th opening from Naruto,fighting dreamers it is called as for the endings my favorite from all the times is Fukai mori by Do as Infinity!

ending to spice and wolf

The second OP for Katekyo Hitman Reborn called Boys&Girls... gosh whenever they show the part with the Varia team standing on this mountain/cliff thing I feel myself squealing on the inside

the song from tengu tenge is the best very funky what youy call

Well this is hard because I've watched a lot of anime. But I think I can narrow down the opening song to Rosario + Vampire Capu2 opening them. I love it!
