^ Me too. You can clearly hear her say "time" in her In The Flesh performance.

I like Ayu's version but her Japanese pronunciation annoys me half the time. She's putting too much stress on every separate syllable. It. Sounds. Like. Someone. Talking. Like. This. She's been doing that for while, but because Utada tends to do the opposite, it really stands out in this song. I guess you'd have to know Japanese to really hear it.
Her English is spot on, though!
