namie has like a year break before having a new single, if that's what the user meant.
example:
60s/70s/80s = 2008
WILD/Dr. = 2009
Break It/Get Myself Back = 2010
she releases one single a year (at least since 2008), and then an album every 2 years. i think that's a long wait compared to ayu
but yea, if that user meant utada instead of namie, then..ignore me
