It's no secret that the Beatles are a legend. It's also no secret that their music is a living legend (of course, two of the Beatles, George Harrison and John Lennon, have gone to the big rock concert in the sky!).
 
However, there are few bands that achieve such success, in such a short span of time, as the Beatles have.
 
Why? Well, the Beatles had an incredible energy and massive crowd draw that few bands today are able to embody. Furthermore, too many modern bands break apart far too early today--they can't survive themselves.
 
In addition, the band was part of a modern phenomenon--a first time ever rock event, so to speak. Moreover, the Beatles music was able to survive world wide long enough to create the legend, and the band was able to survive long enough to crank out the incredible amount of music they produced.

Beatles music is still popular today--a testament to their great sound and the power of those original lyrics--and it is available in many electronic and physical formats, one of which will match almost any listener's preference.
