[Javaweb]

One Piece opening 11 share the world

Hitman reborn opening 8 listen to the stereo

Eureka 7 opening 3
Fmab opening 4(chemistry-period)

[Revengedace]

I love Fullmetal Alchemist Brotherhood opening 1

[Ghan]

Yu Yu hakusho - Smile bomb is the best opening of all time

 

[Drakengard]

Right now it's Steins;Gate. It's kind of a trend that the latest animes I watch get their OSTs/OPs/Endings stuck into my head >_> Cowboy Bebop and Samurai Champloo are next on the line xd

Spoiler

Also I find that a lot of openings seem to "grow" on you overtime instead of it being epic the first time (but not always).
