I love Utada's music more and more with each release. These two songs have a lot of dance element to it, which reminds me of her English Exodus album, but with a more mature sound, I suppose. She actually uses the beat of the chorus of her songs on the Exodus album in part of Kiss & Cry, which is pretty cool. I think she's one of the only artists that I'm into that just gets better and better with every album.
I think my favorite is Beautiful World because I like sing the BEAAAUTIFUL BOO-OOY part out loud.
