Listening to Beatles music now. Will love them forever. I think the short window and their catalog of music is even more impressive as the years go on. They made basically all of their original music, multiple movies, and toured incessantly for the 1st half of those 6-7 years from 1963 to 1970. There will never be another run like that.
I like the Stones, but they have not had the lasting affect on me as the Beatles have. I like a few of their songs, but I was not as impressed with them as musicians as I was with John, Paul, George and Ringo. And Paul and Ringo are still out there too!
Just my taste.
