British folk-rock singer Passenger's "Let Her Go" also fell one spot to number three, according to the Official Charts Company, which compiles the weekly rundown. American rapper Macklemore's "Can't Hold Us," recorded with producer Ryan Lewis and singer Ray Dalton, was unchanged in fourth position. In the album chart, Daft Punk went straight in at number one with new entry "Random Access Memories," knocking Scottish veteran Rod Stewart's "Time" down to second place.
