Black
Kabuto
Den-O
Fourze
Gaim
Drive

Okay, this is my new list: W-B-X (W)
SURPRISE Drive (Drive)
Climax Jump (Den-O)
Anything Goes (OOO)
Switch On! (Fourze)

To be perfectly honest I dotn dislike any of them. Even the second Hibiki opening the one I never listen to is still not that bad of a song.

Take It a Try (sung by Ryoji Morimoto aka Hajime)
Wanna Be Strong (sung by Takayuki Tsubakai aka Kenzaki Kazuma)
Elements (sung by Rider Chips)

Elements (Blade)

Surprise Drive

Kuuga
Blade both openings
Kabuto
Double
Gaim

Oh I love all the theme songs (Showa and Heisei) I suppose 555s theme song is my favorite though.

Believe Yourself is also a good theme.

I like all the Heisei ones (except Faiz...), and I've never really listened to the Showa ones. My favourite is probably Break the Chain, with WBX second and Don't Live More third.
