Whitneys Music all of a sudden in demand

This just frys me. All of a sudden Whitney Houston's music is flying off the shelves. Wasn't her music just as good when she was alive???  You either like her music or you don't, dead or alive.  Did her music all of a sudden get better?  What is wrong with people?  It's kind of like when someone dies, all of a sudden people have all kind of nice things to say about them as they lay in the casket. Why the heck didn't you say that stuff when they were alive??  And to their face???  GGGRRRRRRRR
