Her single "Someone Like You" is spending a fifth week atop Billboard's Hot 100 song chart and her singer's prior single, "Rolling in the Deep," led the Hot 100 for seven weeks beginning in May, making Adele the fourth woman in the chart's history to reign for at least five weeks with multiple songs in a year, Billboard reported Wednesday.
