"Since the beginning of 2006, only the Beatles have sold more "catalog" albums in the U.S. than AC/DC -- also without licensing their music to iTunes. Among the six best-selling catalog artists during that period, the act that sold the most individual songs digitally -- the Rolling Stones -- sold the fewest albums, digital or physical. That is important because while the Stones' six million single tracks sold may seem impressive, they represent low-cost, low-profit transactions. Album sales, on the other hand, are much more profitable."
