Losing out on half of its streaming points by dint of the new chart regulation that downweights songs that have been on the chart for more than nine weeks and have seen their sales fall against the market for three weeks in a row, Despacito still tops the charts for most paid-for sales (25,751) and most streams (6,247,293) but falls to No.2 on the singles chart, ending its second run at the summit on combined notional sales of 46,575 copies.
