As he has gotten older Mitch Albom has become more definite in his likes/dislikes and more condescending towards those who do not share them. I like some of the Beatles music but I would never try to argue seriously that any group is
the best as Albom does in his piece. If he wants to argue that
he liked the Beatles the best or they had the most influence on him that's a different kettle of fish. Music enjoyment is thoroughly subjective. By Albom's own admission there are huge swaths of music, even pop music, that he doesn't know anything about or doesn't like.
For the most part people tend to think that the music around when they were young and/or discovered the opposite sex is always better than the "garbage" that kids listen to today. Just human nature..
