It's Either Good or It Isn't

"Good music is good music.  I'm not concerned with whether someone who listens to me is old or young. In fact, in many ways, I'm not interested in the young at all.  I'm interested in age. People learn to live properly when they get of an age, you know? 

"The late Duke Ellington once said to me that he was really offended by the word 'category.'  Music has no category; it's either good or it isn't, and I sing good songs, great songs, written by the best songwriters. It's that kind of quality that makes them last. Trust me, people will be singing these songs forever."  ~Tony Bennett (source)
