The chart was founded in 2004 and was first published on 1 September that year. The first ever number one was "Flying Without Wings" by Irish boy band Westlife. Since then, , 500 different tracks have reached number-one on the UK Singles Downloads Chart. The following table lists those artists. The totals do not include non-credited appearances (such as those on multiple-artist charity ensembles), although they are listed below.
