I was a bit irritated by all the millennials saying the Superbowl half-time show made them feel old. The 15-minute musical extravaganza at Sunday’s game was a tribute to the golden age of hip hop and featured Snoop Dogg, 50 Cent, Mary J. Blige, Eminem and Dr Dre. The reason it made so many people in their thirties and early forties feel a bit long in the tooth is that all artists are now candidates for the Hall of Fame.
