I have a craving for more cowbell
I would say that the opening for muv luv alternative total eclipse has a pretty kickass opening despite being a pretty subpar anime.
...I cant ignore SnK's opening.. its just so.. epic.
But One of my all time favorite Opening and Ending Soundtracks were from Full Metal Panic!!!!! and its Series!!!
...it literally puts LSS on me!!! :)
screw the rules. I am the rule.!!
Not an actually opening, but it fits so well that I might as well share.
Oh there are so many opening songs that are so good. I don't usually care for listening to them beyond the full song instead of the TV broadcast cuts. But here is my current list. Most are older shows and some I didn't really care for the show but the opening song is what catches me. The opening videos that they create for most shows are just cuts from episodes and don't really do much for me in most cases. These I list here are not bad, but it is the music.
From way back when... Aa Megami-sama OVA Opening - "My Heart iidasenai, Your Heart tashikametai" by the Goddess Family Club
And again in 2005 - Aa Megami-sama TV - "Open Your Mind ~Chiisana Hane Hirogete~ (~Spread Your Little Wings~)" by Yoko Ishida
And the follow up season - Aa Megami-sama: Sorezore no Tsubasa - "Shiawase no Iro" ("Color of Happiness") by Yoko Ishida
Needless to say I really like Aa Megami-sama, mainly for the openings but the shows are good also.
Other I like are:
Yumeria - http://youtu.be/mANWPaL7Kpo
"24 Jikan Aishiteru" by Moyu Arishima & Tamaki Nakanishi
(Not a very good show, but the opening song is so catchy)
Aquarion EVOL - http://youtu.be/45M9ASlutIw
"Kimi no Shinwa—Aquarion Dai Ni Shō" by AKINO with bless4
(The show was not good in my opinion, but the full version of this song is awesome)
The World God Only Knows
Season One - "God only knows" by Oratorio The World God Only Knows
Season Two - "A Whole New World God Only Knows" by Oratorio The World God Only Knows
Season Three - "God only knows -Secrets of the Goddess-" by Oratorio The World God Only Knows
Those three openings played back to back will give you about 25 minutes of some of the best over all music ever put to an Anime series. I listen to those three openings a lot!
Anime His Radio - anime-hits-online
Arpeggio of Blue Steel intro ( Savior of Song-nano )
Black Rock Shooter intro ( Black Rock Shooter- supercell and Hatsune Miku)
Nisemonogatari Intro ( marshmallow justice)
Bakemonogatari outro (Kimino Shirinai Monogatari- supercell)
Angel Beats! outro (Brave Song- Aoi Tada )
Ononoki has invaded your wardrobe.
