Grammies doesn't make careers or put food on the table. Madonna waited 20 years for her first Grammy for her music (and 10 years for a concert movie).
Grammy voters are conservative like school teachers and can't keep up with changing tastes in the outside world. See how late they were to acknowledge Bob Marley (United Nations awarded him a medal in 1978 and he died in 1981), 30 years too late?
10 million albums sold means a large amount of people that might also buy PRISM tour tickets.
