Fair enough.  But for me, and I suspect many others our favourite music is rock (alt-rock and grunge are subgenres).  I rarely listen to light pop.  So if MJ was better than Britney, it's almost irrelevant.  90% of my favourite music was made in the 90s.

It's like saying that the Florida Panthers are a better NHL team than Washington, because James Reimer is a better back-up goalie than Philip Grubauer.

If you are more of a pop fan, then yes I agree the 80s were better.
