Top 5 because of their skill at songwriting and production technique. They changed everything. They also stopped performing live shows and lost status as greatest "band". So many of their songs are timeless classics. Other songs haven't aged well and are probably only remembered because they were Beatles songs. I was a huge fan when I was a teen in the 70s, but now think that a lot of their music sounds more like a Lerner and Lowe Show Tune than Rock n Roll.
