I was very tempted to pick Queen of Hip Pop, but I figured more people are likely to pick that one and her older albums need more love around here.
So I went with Concentration 20.
Seperate topic: Does anyone know if Namie changed her choreographer in 2006? Because I have felt that ever since then her choreography has not been as good. I was just reminded of this tonight when I watched her 03/04 tour - her dance and choreography was amazing then but from Live Style on I've noticed a significant change in the quality of the choreography.
