Who runs the world? The Knowles sisters when it comes to sisters breaking music records.=
Beyoncé's sister Solange's latest album, "A Seat At The Table" earned her her first No.1 on the Billboard 200 chart.
It's also a family milestone for Solange and Bey, who may be the first
sisters to both earn a No. 1 album on the Billboard 200 as solo artists.
