As it leads Billboard's Nielsen BDS-based Mainstream Top 40 chart for a sixth week and Rhythmic for a seventh frame, Robin Thicke's "Blurred Lines," featuring T.I. and Pharrell, climbs 3-1 on Adult Top 40. (The song marks the first No. 1 on the lattermost chart for all three acts.)
The Adult Top 40 coronation of "Lines" continues the song's high-profile summer. A partial recap: the track has topped the Billboard Hot 100 for nine weeks; set the mark for the greatest weekly audience (219.8 million, according to BDS); and become the first song to sell at least 400,000 downloads in each of four weeks, according to Nielsen SoundScan.
This week, "Lines" adds another achievement: the song is just the second – and the first in more than 14 years – to top Mainstream Top 40, Rhythmic and Adult Top 40 simultaneously (dating to the Adult ranking's March 16, 1996, launch; Mainstream and Rhythmic each premiered the week of Oct. 3, 1992). The week of June 26, 1999, another dance-leaning pop culture juggernaut crowned all three charts: Ricky Martin's "Livin' La Vida Loca." That week, the song shimmied 3-1 for its lone week atop Rhythmic while amid a seven-week Mainstream rule and a six-week Adult domination.
Also impressively, with "Lines" at No. 1 and Imagine Dragons' "Radioactive," Maroon 5's "Love Somebody" and Zedd's "Clarity" (featuring Foxes) at Nos. 2-4, Interscope is the first label ever to boast the top four Mainstream Top 40 titles concurrently.
