Utada still Top 4 iTunes US

The great thing is not just she wrote all the song but also the producers.

She use 2x producers, one is "Stargate" and another is called "Tricky"

Stargate = Rihanna "Don't stop the music"

Tricky = the producer of Mariah Carry "Touch my body"

Another song from "This is the One" of my favorit is this song.

"On and On" produced by Tricky
