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.
