Manic! by Plumb for Anemone from Eureka seveN, definitely.
3nodding Hheehee, me and Nekuma were discussing how much that song fit her xD

I saw an AMV once for Ryoko [ Tenchi Muyo! ] to Sweet Escape by Gwen Stefani. It fit o_O;;; If you take out all the bad things that happened to her in her past it fits xD. I don't know what a song for Ryoko would be if you take in the whole picture, definitely something better than Sweet Escape. Hmm...I shall have to think of one! =D

And every time I watch Samurai X: Trust and Betrayal I hear Angels and Airwaves "Start the Machine" in my head.
EDIT -

I think "White Flag" by Dido when I think of Ahiru/Duck/Princess Tutu, because through it all, she have some doubts but overall she never really gives up until she's done all she can do.

And when I hear "It Hurts" by Angels and Airwaves I think of the slutty Nana xD;;;. 'Course, i haven't read past volume 1 yet, so she may get better....
