The Chris Brown and Young Thug collaboration “Crazy” has peaked at No. 1 on the Billboard Hot R&B/Hip Hop Songs chart after its 32nd week on the list. The single, which debuted at number 33 in May, rises from No. 3 on the chart dated Dec. 26. “Crazy” secures Brown’s sixth No. 1 on the chart. He last led when he, Drake and Lil Wayne all featured on Nicki Minaj’s “Only”, a one-week leader in 2014. In terms of leading roles, the new chart champ marks the R&B veteran’s first since “Look At Me Now”, featuring Busta Rhymes and Lil Wayne, clocked eight weeks in charge in April-May 2011. Young Thug, meanwhile, banks his second Hot R&B/Hip Hop No. 1. He previously led two months ago, when Travis Scott’s “Franchise”, featuring the rapper and M.I.A, debuted atop the Oct. 10 dated results. With a 32-week ride to No. 1, “Crazy” ties for the third-longest trip to the top since the Hot R&B/Hip Hop Songs chart’s genre-wide survey began in 1958.
