It's amazing to read people's musical likes and dislikes. I think it would be easier for me to list ONLY the musicians I don't like. Currently, I listen to less new music than I once did. I'm not sure if I can tell you the name of any musical group or artist that has caught my ear since the "turn of the century".
I'm most critical of the lyrical message and good to excellent (unique and creative) musical/instrumental skill an artist or group puts across. I myself sing and write lyrics and have composed(?) a few songs (none anyone's heard). To me, good music is just bliss. If I can sing to/with it and it conveys a (valuable) message without being trite, then I usually enjoy it.
And the Beatles are CLASSIC! Read their lyrics and you will know. The pictures they painted with words and music are DEEP. Very often the depth is not seriously intellectual but simply playful and, earlier on, "sexual" as in full of innuendo and double/triple meaning(s). But as a writer, I know how seriously difficult it is to achieve such complexity in an apparently "simple" form. They were poets and composers and pretty nice to very good singers (well, Ringo, not so much).
Yea, maybe they were, the first "boy band" (not really because by the time they hit the US they were all in their early to mid 20's, except maybe Harrison at 19). NO
" since has been able to come anywhere near the talent of any one or combination of McCartney, Lennon, Harrison. The Beatles were marketed very well by their shrewd manager Brian Epstein and assisted greatly by their producer George Martin but that can not detract from their own personal talent.
Lennon, my favorite, was a political radical who "fought" peacefully
for what he believed in. He was one of the first (pop) musical entertainers to capitalize on his fame in the pursuit of positive political change. Neal Young being another. Hmmm, how many more?
