I could never understand it either. If I had to choose a beatle, it would be George....My sweet Lord...or Ringo.
Let me say this about that. I had loved the Beatles for years before John died, and in fact was making friends with the guy I mentioned above based in part on his further educating me about them. I loved their music, but until John died, he had to be my least favorite. This was based on the fact that he had the reputation of being the angry, edgy one and could make remarks ranging from inappropriate to scathing. I had had more than enough of being the target of others' angry edginess and had no use for it. Despite Paul having had some set-tos with the others, I loved him--always thought of him as the pretty, friendly, cuddly one. Still love Paul despite his drawing some flak from his response to John's death and other things. Did love Ringo until I heard a few stories about him having an attitude, being mean to fans and possibly even meaner to non-fans. (I haven't looked into such stories as to whether they are true let alone typical.) One thing I
do love about Ringo was he was the only Beatle to meet Ray Bradbury. Ray himself told me that when Ringo saw him, he became so excited he ran over to greet Ray, and actually fell over a chair, somewhat hurting himself. So anyone that enthusiastic about Ray can't be all bad. I also like George because I have always liked rather deep, serious guys, and George was very attractive in his own way too.
So because I thought of John as being the angry, edgy one, every song I thought was weird or didn't like I sort of set aside as John's song, and those I liked I embraced as Paul's. Not until after John died did I become aware that he was partially or totally responsible for many of my favorites. His death also brought me close to some people and mended some fences. It was very much like President Kennedy's death, especially for people who could not remember that. People who do remember it still recall, and sometimes even feel, a very strong emotional response despite having learned uncomplimentary details about Kennedy since. So I explain any reverence I may have for John that way.
