Which animé has the catchiest theme tune?

[Red Pawn]

Dammit, man, I had things to do. Now I have to re-watch the entire series.

OP: A little Baccano never hurt anybody.
Hell. Now I have to watch this again too.

As much as I loved Tank! from the Cowboy Bebop OP, I've heard that show so many times over the years on CN, that it's actually starting to grate on my nerves a little. It's still solid though.

 

[vanthebaron]

Kenshin op 1. Starts with heavy metal ref then goes to j-pop.

 

[GothmogII]

Golden Boy hneah. Everything else seems to have been already mentioned.

[Berserk Seraphim]

[sageoftruth]

Cowboy bebop of course.

Yeah! That and the opening for Baccano both made me decide to give Jazz a chance.

 

[TehCookie]

Here's some more catchy ones since people seem to have mistaken this for favorite opening...

Spoiler: Bakemonogatari - Renai Circulation Bleach - Alones Gintama - Mr.Raindrop Katanagatari - Meiya Kandenrou

 

[Arkonnan]

personally, I always liked the gurren lagann opening.

 

[Diablo2000]

Street Fighter 2 V... Fuck what people say, that anime is awesome...

http://www.youtube.com/watch?v=QBdbvBiTFsE

 

[Draithx]

While not the best opening definately one of the most catchy ones: Second opening to K-on!! - Utauyo!! MIRACLE
Though I might be biased considering I've had that song playing on repeat the last few days.

Catchiest this season is imo the opening of The World God Only Knows.
Best ending is Kimi no Shiranai Monogatari. God I love that song.

 

[direkiller]

Does Pokemon count?

Gotta catch 'em all...

i don't think so seeing its a song written in English solely for the English version
if they do count Rock the dragon wins

 

[neoontime]

I'll add to the FMA list and put this great tune.
Edit: Damn I can't see what I posted, something wrong with my computer or something?
Edit 2, oh wait now I got it.

 

[Always_Remain]

This song is basically the only thing that got me through the endless eight.

Are you referring to that shit during the middle of the second season? Nothing has ever made me rage so much watching animation than that particular waste of animation.
NGE's got it for me. Just because it's so disconnected with the feel of the series.
HOTD is a good runner up and it DOES fit with the series.

Yes. Yes I do mean that eight episode abomination that could have been solved in two MAYBE three episodes. I agree with HOTD too.
