Ultratop 50 Singles (Wallonia)

Ultratop 50 Singles is the chart of the best-selling singles in Wallonia.^[1] The Ultratop has existed since 31 March 1995. The Flemish counterpart of this chart is called the Flemish Ultratop 50. Until 4 September 2010, the chart consisted of 40 records and was called the Ultratop 40. There are twelve different charts under the Walloon Ultratop.

The Ultratop 50 Singles list is broadcast on Bel RTL on Saturdays between 12 and 2 pm.

Both the Walloon Ultratop 50 and the Flemish Ultratop 50 were compiled purely based on sales data. Airplaywas initially not included. This data is collected by the international market research agency Nielsen. Every Saturday (or Sunday), the number of copies sold per single is collected from a representative number of stores. To prevent fraud , this data is processed using an anti-fraud procedure. If companies, artists, or consumers deliberately attempt to manipulate the charts , this is corrected. For each list, the sales data from the past two weeks is calculated. This prevents major fluctuations in the chart. All Ultratop charts are announced on Wednesdays and appear on the website on Thursdays. The broadcast is on Saturdays.
