In my opinion only......
To say that the Beatles suck is like saying that the BeeGees suck. In order to say that, one must only listen to their top 40 hits.
If one would like to appreciate either band, one must listen to all of their music.
I know the top 40 stuff of the Beatles. Those songs are part of the soundtrack of my life. Because of an older sister who won a "Hard Days Night" album from WIXY 1260 in Cleveland, the songs are familiar and comforting. I am not a big fan, but they did change our culture. I can't say for the better.
The BeeGees are the same. Because of the "Saturday Night Fever" era, people think their music is garbage. However, listening to the "Nights on Broadway" era of their music is my favorite.
But all in all, it's opinion, nothing more. If someone is stating an opinion, I feel that they should hear the entire library.
