Same as with me, growing up in 1950's. One can grasp that by looking at AM radio popular music charts which show the broad range of music that was broadcast before rock and roll sprung up. From religious themes, movie musicals, torch singers, country and western, to the ridiculously humerous ones like "All I want for Christmas is a hippopotamus", and of course, Lawrence Welk and Mitch Miller
Once again "PC diversity" strikes with modern music in practice virtually segregated, millions missing out on the marvelous spectrum that music offers.
You could be of any race, ethnic background, sex, and religion and it didn't matter at all! We all love Nat King Cole, Eartha Kitt, Tennessee Ernie Ford, Perry Como, Kate Smith, and on and on and on.
We heard classical music when watching cartoons, every kind of music on The Ed Sullivan Show, many different kinds of music in movies, radio and T.V. shows, and radio had, as you mentioned, just about every kind of music on AM pop music stations.
PC crap just pigeonholes and divides people now and it's stupid! Our nation has been Balkanized.
