The singer is back and on fire ::: Congratulations are in order for Janet Jackson, who’s single “No Sleeep” (featuring J. Cole) has made it to number one on the Billboard Adult R&B songs chart! If this is anything to go by, Janet definitely hasn’t lost her mojo. The chart is generated based on the week's most-played adult R&B songs, ranked by radio airplay detections on adult R&B-formatted stations, as measured by Nielsen Music.
