The boy band is K-pop's fastest male group to top the chart to date.
The boy band's electro/hip-hop/pop hybrid single debuts at No. 1 on Billboard's World Digital Song Sales chart giving the group their first chart-topper on the list. "Simon Says" sold 2,000 copies and logged 2.1 million on-demand U.S. streams (audio and video combined), according to Nielsen Music, for the week ending Nov. 30. It marks one of the band's best sales week for a single, but the result does not surpass "Regular" which sold 3,000 copies when it debuted at No. 2 on World Digital Song Sales in October.
