The Beatles were a really, really good pop band - much better than typical.

Can't Buy Me Love, Hard Day's Night, Help!, Day Tripper, We Can Work It Out, Paperback Writer, Yesterday, Nowhere Man are mid-career Beatles, 1964-66. Most charting bands don't produce memorable pop songs like this over and over.

And then they made the more ambitious albums.

McCartney proved again later that he is an outstanding pop musician. Maybe I'm Amazed, Live and Let Die, etc.
