Congrats to the duo. Taken from Billboard:
The act becomes the first duo in the chart’s five-decade history to send its first two singles to No. 1…
Macklemore & Ryan Lewis’ “Can’t Hold Us,” featuring Ray Dalton, rises 2-1 on the Billboard Hot 100, becoming the pair’s second leader. With prior hit “Thrift Shop,” featuring Wanz, having reigned for six nonconsecutive weeks, the act is the first duo to take its first two singles to No. 1 in the Hot 100’s almost-55-year history.
