RAINBOW will only be in next year's list ....can't you see the single traveling from Utada is in this year chart? It was released last year (2001) but in the end of the year, so they considered it as being from 2002 since it still was selling a lot....the same will happen to RAINBOW...it will sell a lot in 2003 so it's still not the time to include it in the years chart!
