Definitely most of the OPs and EDs in Gundam SEED and SEED Destiny. "Anna ni Issho Datta no ni", and "Reason" in particular.
Both the songs from Gundam 00 are crazy rockin. Deathnote has some great songs! Love Nightmare, but Maximum the Hormone has gotta be one of the sweetest jbands ever ^_^
Both seasons of GITS had incredible openings. And then songs like "Duvet" from Lain and "Light before we land" from Gunslinger girl I love too...
And for pure win you can't beat the GTO theme ^___^
I could go on naming forever really. I love music.
My top 10 OP|ED:
Welcome to NHK ED - Odoru Akachan Ningen
Outlaw Star OP - Through the Night
Ikkitousen Dragon Destiny OP - Heart&Soul
Ikkitousen OP - Drivin Through the Night
Higurashi No Naku Koro Ni OP
King of Bandits Jing OP - Shout It Loud(I've always liked Scudelia Electro)
Peace Maker Kurogane OP - Hey Jimmy!
Black Lagoon OP - Red Fraction
Genshiken ED - Biidama
Claymore ED - Danzai no Hana
I like Colors by flow, but my current favourite one is "Ash like snow" by the brilliant green (from Gundam 00). Although I feel the music video could of been better(so I post the intro), the song is good:

I'm surprised with all the UVERworld songs people have mentioned, "Colors of the Heart" the 2nd Blood+ OP hasn't been mentioned. That's on the top of my list.
My all time favorite is, Mikio Sakai - Tabidachi no Kane ga Naru (s-CRY-ed ED for last episode). If you haven't heard it, its totally worth downloading, even paying for if you have to.
Eufonius - Idea (Noein OP)
Hav - Hey Jimmy! (Peacemaker Kurogane ED)
Yasuaki Ide - Magma (s-CRY-ed Insert)
Yasuaki Ide - Reckless Fire (s-CRY-ed OP)
Mikio Sakai - Drastic My Soul (s-CRY-ed ED)
Tomoko Tane - Broken Wings (Trinity Blood ED)
Dress - Buck-Tick (Trinity Blood OP)
Takahashi Hitomi - Aozora no Namida (Blood+ OP1)
Nightmare - The World (Death Note OP1)
Nightmare - Alumina (Death Note ED1)
The Pillows - Ride on Shooting Star (FLCL ED)
UVERworld - D-tecnolife (Bleach OP2)
Home Made Kazoku - Thank You!! (Bleach ED2)
Youna - HÅkiboshi (Bleach ED3)
Skoop on Somebody - happypeople (Bleach ED 4)
Bana - Half Pain (Witch Hunter Robin ED)
Kuribayashi Minami - Tsubasa wa Pleasure Line (Chrono Crusade OP)
The majority of the Inuyasha endings, especially "Come," "My Will," and "Fukai Mori."
Anything from Yoko Kanno, she's fucking awesome.
God, there's so many I have to stop before the list gets too long.
I think every UVERworld song is great :
* D-tecnoLife was used as the 2nd opening to the anime Bleach.
* CHANCE! was used as the opening in the game Bleach: Heat the Soul 2.
* Colors of the Heart was used as the 3rd opening for the anime Blood+.
* SHAMROCK was used as the ending theme for the Japanese Drama; Dance☆Drill.
* Kimi no Suki na Uta was used as the theme song for the show; Koi Suru Hanikami!
* endscape was used as the 1st opening for the anime Terra He "Toward the Terra."
* Ukiyo Crossing was used as the theme song for the Japanese Drama; Hataraki Man
I have all the singles except "endscape" and "Ukiyo Crossing"
"Sora Iro Days" is as epic as its' series (Tengen Toppa Gurren Lagann for those who're missing out), and "Give A Reason", the Slayers NEXT OP, is pretty good. Same goes for "I Say Yes" from Zero no Tsukaima season 2.
Yay, someone else has seen Goshuushou-sama Ninomiya-kun as well! The OP and ED are good, but only if you like upbeat music. The anime is kinda like brainless fanservice, so watch it if you feel like brainless fanservice.
I suppose my favourite anime OPs and EDs would have to be anything by:
Rie fu
Most stuff by Nana Kitade Younha (though I did get kind of sick of Houkiboshi) L'Arc en Ciel - "Ready Steady Go" and "Niji" (if you include anime movies) BoA - "Someday Somewhere" (It's so hard to find a good translation of it) Aya Hirano (just because of "God Knows...", it's an awesome song) surface - "Yume no Tsuzuki he" (haven't heard too much from this band, but this song is great) Rie Tanaka (the songs from Chobits are the best) Cheiko Kawabe - "Be Your Girl"
And anything by UVERworld. Seriously, anything. One of the best bands in my book so far. And of course, I always have to say, when recommending music, Ayumi Hamasaki. She's done a song or two for anime, don't remember which, but she's one of the best J-Pop stars there are. Go listen to Ayumi Hamasaki and UVERworld, NOW!
I ramble too much...
Edit: Damn, I forgot about ROUND TABLE ft Nino, they are awesome...
T.M. Revolution - resonance (Soul Eater) OP
369 - Kasumi (Daughter Of 20 Faces) ED
Boa - Duvet (Lain) OP
Sheryl - Diamond Crevasse (Macross Frontier) ED
Triangular (macross frontier) forgot wheter it was OP or ED but yaeh tis great
