Pretty cure has great fighting scenes too, shounen anime must learn from pretty magical girls. No, not dressing like pretty magical girls with rubber hoods below.

I sometimes find myself singing/humming the Futari wa Pretty Cure theme.

True.

Futari Precure still takes the cake on the fighting though for me. (Especially at 0:48.)

I couldn't find the scene on YouTube subbed. :(

Idol songs were made to stick into your head, combine electronic music and cheerful voices to cheer you will definitely stick in.

It is like Heavy Metal + Piano + AV actress moans = Idol Music

Definitely will stick like seed.

I generally don't get OPs stuck in my head, as there's not enough room with all the other tunes bouncing around up there.

Best music is music you hum out of the blue while strumming!
