Robin Thicke’s unstoppable single “Blurred Lines,” featuring Pharrell and T.I., is sitting pretty at No. 1 once again this week, claiming the title of this year's longest-running No. 1 song (so far) after passing Macklemore and Ryan Lewis' "Thrift Shop," featuring Wanz. But this week, Thicke adds to his achievements as the track has now reached nearly 243 million radio listeners, breaking the previous record of 188.8 million.

"Lines" previously broke the record for biggest single-week downloads so far this year when it racked up more than 428,000 during the week ending June 23.

The song is the title track to Thicke’s upcoming new album, which arrives Tuesday (July 30) via Star Trak/Interscope Records on July 30.
