For myself growing up in the 60's it was mostly The Beatles that drew my attention as well as many others.
As for the entire body of work by them, there might never be another four piece musical group like them.
Sad to think that the younger generation today only has thug rap/hip hop trash or Britney Spears to listen to.
The quality of music may have diminished itself when it started to become more of a visual expression of art rather than
purely audio form of entertainment.
Just one of my favorites out of many.
