Well, where else did you imagine this list was going to end up? There's only one star who was fit to sit at the very top, and that's 'The King' himself. He could have been born in any of the fifty states, and there's still nobody else who could have held a candle to all he achieved. Elvis Presley popularized rock and roll, transcended music to become a film star, opened the door for the Beatles and generally became a legend within his own lifetime.
Such was the level of Presley's success that when he was given the Lifetime Achievement Award by the Grammys in 1971, he was still only 36 years old. No solo performer in the history of music has ever sold more records, and it's likely nobody ever will. Ever since his untimely death in 1977, his hits have been performed by impersonators in almost every country in the world. More than forty years after he left us, Presley remains a one-man industry, generating over $30m a year.
