I didn't watch it, not my thing, but certainly wouldn't think of disparaging the music or anyone who enjoyed it. My 24-year-old child said it was great.
We have really forgotten how to live and let live in this country. A hip-hop/rap Super Bowl halftime show certainly didn't change/impact my life, so why should I care? Snoop is as mainstream as it comes these days but they're not chasing my demographic anyways.
Maybe next year they should have the NY Philharmonic, great musicians who can play any kind of music. Or an HCBU band to rock the house.
