‘Blurred Lines’ Crowned Billboard's Song of Summer

Robin Thicke's "Blurred Lines" (featuring T.I. and Pharrell) officially clinches the top spot on Billboard's 2013 Songs of the Summer chart.

Billboard's annual Songs of the Summer running tally tracks the most popular songs based on cumulative performance on the weekly Hot 100 chart from Memorial Day through Labor Day.

According to Billboard, "Lines" took hold of the top rank on the Billboard Hot 100 the week of June 22 for its first of 12 frames at No. 1. (It cedes the summit to Katy Perry's "Roar" this week.) It ties two other songs for the most weeks tallied at No. 1 on the Hot 100 encompassing charts covering Memorial Day through Labor Day: Mariah Carey's "We Belong Together," the top summer song of 2005, which collected 12 of its 14 total weeks on top in that span, and Brandy & Monica's "The Boy Is Mine," which notched 12 of its 13 weeks at No. 1 in the Songs of the Summer chart's tracking period in 1998.

"Lines" has dominated multiple charts over the summer. In addition to its Hot 100 reign, it set the record for the highest weekly audience (228.9 million, according to Nielsen BDS) in the 23-year history of Billboard's Radio Songs chart, passing Carey's "Belong" (212.2 million). It leads the list for a ninth frame this week. The song also scored the Hot 100's top Airplay Gainer award for a record 10 weeks.

Even as the heat of summer fades, "Lines" continues to top a host of surveys. It rules R&B Songs for a 16th week, Hot R&B/Hip-Hop Songs (for a 13th), Rhythmic (10th), Pop Songs (ninth), Adult R&B (fifth) and Adult Pop Songs (fourth). It's sold 5.4 million downloads to date, according to Nielsen SoundScan.
