The 1Xtra Chart is a discontinued weekly record chart based on sales of singles in the United Kingdom. It listed the 40 biggest-selling urban music songs released within a three-month time period,[1] and featured genres such as hip hop, R&B, dancehall and rap.[2] The chart was compiled by the Official Charts Company (OCC) on behalf of the UK music industry, and each week's new number one was announced on The 1Xtra Chart at 1 p.m. on Saturdays on BBC Radio 1Xtra.[3] Adele Roberts took over from Sarah-Jane Crawford in spring 2012, and it had been hosted by Ronnie Herel until December 2010.[4] The chart was also listed on the official websites of both BBC Radio 1 and the OCC.
The 1Xtra Chart was launched during October 2007.[1] Its first number one was "Valerie" by Mark Ronson featuring Amy Winehouse.[2]
