Travis Scott‘s team is publicly disputing the overall chart placement of the rapper’s mixtape Days Before Rodeo, which came in at No. 2 behind Sabrina Carpenter‘s No. 1 album Short ‘n Sweet on last week’s Billboard 200. Scott’s team says that Billboard and Luminate’s sales measurement is “unreliable and incomplete,” while alleging that nearly 1,300 units of Days Before Rodeo that sold ahead of the cutoff time were ultimately not counted toward the first week’s sales. The letter was sent by an unnamed rep at Cactus Jack Records to Luminate, with claims that Scott (who recorded slightly over 361,000 sales) would have sold just enough units to edge out Carpenter’s 362,000 sales to No. 1 on the Billboard 200 chart.

“This was never about Travis versus Sabrina — it’s about the integrity of the process and the questionable tactics used in U.S. charting,” said a representative for Scott. “This could happen to any artist.” A spokesperson for Billboard told Rolling Stone that they “stand behind our chart data and methodology.” (Rolling Stone)
