Wow, what a question!
Well, I remember I was 8 or 9 sitting in my living room, and all of a sudden this commercial came on of this wierd game, with this boy who held a key with a whole bunch of Disney characters. The first thing that got my attention was the song that was playing. I didnt think I was going to like KH so instead of playing the game, I just kept watching and listening to the ending of the game, after a while I actually started playing the game and realized it was great, but anyways, because I was so young I really didnt look Utada up and know about her music until years later when she came out with This Is The One. After listening to that album thousands of times, I decided to try her japanese stuff,I listened to Ultra Blue, and next thing i knew, I fell in love with her music,lol
