Norah Jones - An own music style

After her first internationally successful album "Come A Way With Me" Norah Jones has described their music style jokingly as "Snooze". And then after I rythmischeren the little 'New York City' and 'heard Livingroom Dreams'Session, I waited anxiously for a next album with a' funky touch '.
Why a young vibrant musician it then but prefers to make quiet and relaxing music, you know probably best.
From the standpoint of the musician I can only emphasize that it is much more difficult and challenging to play slowly and quietly rather than loud and fast.
