I've yet to see the whole OP. My video player kept freezing up throughout that part. I guess it's just that awesome
Don't know if it's the right place (sorry if I'm doing wrong), just wanted to post my top 10 openings. To avoid slowering page loading with videos, all pics are clickable (tried when possible, to link to hd videos).
Top 10 :
-10- Gintama, op 13- Sakura Mitsutsuki, Spyair
-9- Samurai Champloo- Battlecry, Nujabes
-8- Durarara !!, op 2 - Complication, ROOKiEZ is Punk'd
7- Naruto Shippuden, op6 - Sign, Flow
-6- Fma Brotherhood, op 4 - Period, Chemistry
-5- Clannad After Story- Toki wo Kizamu Uta, Lia
-4 - Serial Experiment Lain, Duvet, Boa (haven't sen this anime, incredible great op considering it was released in the end of 90's)
-3- Tokyo Magnitude 8.0, Kimi no Uta, Abingdon Boys School
- 2- Bleach, op 13 - Ranbu no Melody, Sid (Have never seen the show, came across the op by chance, and seems that Bleach op & soundtrack are incredibly good)
-1- Ergo Proxy- Kiri, monoral
Honorable mentions :
Death Note, op1, Shiki op2 (Haven't seen the show), Snk op1, and Darker than Black op1
NB- I don't watch so many animes so my choice is fatally flawed.
