Robin Thicke, T.I., Pharrell Williams — Blurred Lines

The 2013 summer juggernaut is back across the global charts, tracked across 25 country and platform charts after a two-week absence. Co-written and produced by Pharrell Williams, sung by Robin Thicke and featuring T.I., the track was one of the defining pop singles of its year — a slinky, Marvin Gaye-adjacent groove that dominated radio before becoming a lightning rod, both for its widely criticized music video and a landmark copyright verdict over its resemblance to Gaye's Got to Give It Up. According to Britannica, Williams cowrote and produced it at the height of his early-2010s hot streak, the same window that produced Happy and Get Lucky. Its minimalist hook and cowbell pulse remain its calling cards — durable enough to keep the song in rotation more than a decade on.
