If it isn't Utada then I don't want to know becasue nobody else deserves to be the first breakthrough other from Utada in my book.
She was born in America, speaks the language fluently and writes all her own music unlike the One Hit Wonder Girls.
not to mention she has 100X better voice then all 4 combined and her songs are better then anything that those 4 girls team of producers and songwriters can ever dream up.
