DRAGON DRAGON BALL!
DRAGON BALL Z!


Actually, i can't stand anime...

Lain has a great intro, Boa's Duvet.

I'm also loving the intro to Chobits, as it is as adorable as Chii. :D

FLCL! and EVA!

And yes, "Fly me to the Moon" is a Sinatra song.

Holy Jebus Christ I'm not the only person who's seen GTO! It sure does have some great tunes.

I like the second theme song better, by Porno Grafiti.

Outlaw star has a fun opening theme song. Hellsing has a great opening.

Still, my vote goes with Cowboy Beebop. Everytime I hear "The Real Folk Blues", I feel like crying. I don't know why. No other song I hear makes me want to cry, and I"m a freaking music major. "Tank" makes me want to rock out.

I'll put my vote in for Trigun - I played it with some strangers at an anime convention in Baltimore last summer...hard as hell! But it came off ok, we managed to get it out before security asked us whose electricity we were using!?!!?
That aside, I think I should mention that I've never seen Trigun or any anime before...so I probably only make up 3/5s of a vote.

Not that these three haven't been mentioned, but in my opinion, it doesn't get any better than Furi Kuri, Samurai Champloo, and Cowboy Bebop. Not only the opening and ending songs for these, but also for the songs in the episodes.

Outlaw Star easily has the best ending themes. There's just two, buy they rock my socks so hard I have to buy a new pair every time I finish watching an episode.

EDIT: Wow... I wonder what ever happened to TerresqueÜ.

If you count movies, then Tekken. Otherwise, the title/credits and the intermission music for Tokyo 2040 is really cool and catchy.
