Is Robin Thicke's "Blurred Lines" officially?
The track, which features T.I. and Pharrell, has earned a seventh week at No. 1 on the Billboard Hot 100 chart, the most weeks any song has spent atop the list this year.
"Blurred Lines" surpassed Macklemore & Ryan Lewis' "Thrift Shop" as the longest-running chart-topper for 2013. That song led for six consecutive weeks in February-April, according to Billboard.
The milestone isn't a record, however -- Maroon 5's "One More Night" topped that chart for nine straight weeks last year, while Gotye's "Somebody That I Used to Know" did the same for eight weeks in 2012.
"Blurred Lines" also topped the digital songs chart for an eighth week, selling 340,000 downloads per Nielsen Soundscan.
