Are pop songs dumb? Study offers evidence

A new study finds that the average hit song has lyrics at a third grader's reading level. The study, completed for ticket seller SeatSmart, found that the average reading level was third grade -- roughly eight years old in the US educational system -- and that it has gone down over the decade. Country music was the most advanced, with an average of 3.3, with R&B and hip-hop last at 2.6.
