The Chainsmokers have scored another week at the top of the U.S. pop charts with their Halsey collaboration Closer.

The duo has extended its number one lead to five weeks, keeping Twenty One Pilots pegged to number two.

Closer also tops America's Billboard Digital Songs, Streaming Songs and Hot Dance/Electronic Songs countdowns.

Major Lazer's Cold Water, featuring Justin Bieber and MO, holds firm at three, while Sia's former four-week number one Cheap Thrills stays put at four, and The Chainsmokers bookend the top five for a second week with Don't Let Me Down at five.
