No one will be surprised at the dominance of The Beatles and Elvis Presley at the beginning of this data visualization from Data is Beautiful. But there may be some surprises for you as the years go by. What did Elton John do in 1997? Oh yeah, "Candle in the Wind 1997," after the death of Princess Diana. And I was surprised that Beyonce didn't stay on the chart all that long. But watch Psy tear right up the graph ...and fall just as fast. -via Digg
