Let's take a peek at the numbers: The Beatles have racked up six diamond albums, 24 multiplatinum albums, 39 platinum albums and 45 gold albums. Now that is some serious bling, no? On top of all that, Macca's plaintive ballad "Yesterday," which originally appeared on the Fabs' 1965 album Help!, is recognized as the most recorded song in pop music. Despite all this impressive data, the ultimate measure of an artist's popularity is the number of tribute bands and albums he or she inspires. It can be argued that The Beatles are second to only Elvis Presley in this category. But what's truly scary is that they just keep on coming!
