Beyoncé’s surprise move in releasing a previously-unannounced album exclusively on iTunes seems to have paid off big-time: after setting a new iTunes record as the fastest-selling album ever, the self-titled BEYONCÉ album has now sold more than a million copies in just five days.

It’s quite an achievement, especially at a time when music downloads may have passed their peak, but as music industry analyst Bob Lefsetz observed (via AtD), it doesn’t mean other artists can expect to pull off the same trick.

The bottom line is Beyonce is a superstar. And superstars get traction. And everybody else is close to ignored. And you become a superstar by having a bunch of money and power behind you.
