Cowboy Bebop - Tank
http://www.youtube.com/watch?v=n2rVnRwW0h8
Jazz and Bebop? In
my anime?! OH HELL YES! Quite possibly, the best opening theme for an anime, ever! No annoying high pitch J-POP singers, no shitty guitarist wanky it for a OP theme, just pure, awesome music! Yoko Kannon is a fuckin'
BEAST!
Cowboy Bebop - The Real Folk Blues

My God, the beautiful voice, that amazing guitar chords, the smooth brass section, the sexy bass grove, the saxophone riff, this ending theme, oh my
GOD it's so amazing.
THE BEST anime ending song of all time!
Lupin the Third - Main Theme

THAT. SEXY. SAXOPHONE. MELODY! So smooth for a smooth gentleman such as Lupin.
Lupin the Third - Love Squall
http://www.youtube.com/watch?v=aSJ2uJpk6Mc&feature=related
Reminds me of a blend of those old black and white 50s romance film score, jazz, and 70s Motown RnB.
Higurshi no Naku Koro Ni - When The Cicadas Cry
http://www.youtube.com/watch?v=rKV195eXg7I
Perhaps the music score of Higurashi is the only thing that Studio DEEN did right. Then again, the guy behind the music of Higurashi no Naku Koro Ni also did the score for the "Ghost in the Shell" movie. Creepy and haunting, cruel and taunting. The song sets the tone of the first season of Higurshi and perhaps, the visual novel, perfectly.
Higurashi no Naku Koro Ni - Main Theme Ai

Haunting but yet, longing for sorrow and love at the same time.
Higurashi no Naku Koro Ni Kai - Taishou a.

Jazzy, which I have no problem with.

Details the story of Kai fairly well.
Umineko no Naku Koro Ni - One Winged Bird
http://www.youtube.com/watch?v=5_vGeHAM4gM
One Word: Amazing.
The choir, the orchestra, and the opera-like voice. Would be perfect for a movie score if song in Italian completely.

OH DESIRE!
Umineko no Naku Koro Ni - Mirage Coridnator
http://www.youtube.com/watch?v=HiGYDcl0Ohk
The anime version of it was a bit...lacking but still was pretty decent. Cant' beat the original however.
Umineko: Ougon Musou Kyoku - Dance of the Golden Butterflys (Stained in the Golden Blood)
http://www.youtube.com/watch?v=AVrJDEPrULk&feature=related
That rock-opera. The first time I had heard this song, my mind was blown away. Everything about tihs song just seem to sew in without seam.
School Days - To The Other Side of Sorrow
http://www.youtube.com/watch?v=MDqeUjt6dxg
If I can get to the other side of sorrow than maybe I won't bang three different girls and be in baby daddy issues.
School Days - Sekai Theme
http://www.youtube.com/watch?v=-bIVu8KITT8
A lovely waltz-like theme for Sekai. Plays when she gives advice to Matoko such as cheating on your girlfriend, fuckin' half the school, and breakin' your girl's heart.
