RAINBOW is one of Ayu's best albums, as far as musical craftsmanship goes. I always looked at it as I am...'s sister album: where I am... is a cohesive musical masterpiece with a raw, edgy style, RAINBOW is a cohesive musical masterpiece with a clean, polished style. It's fantastic.

I think the only thing that went wrong with it is the swiped intro to "Free & Easy". I think something original could have been composed for that without the uncredited help of Éric Serra.
