So we are avoiding issues related to the varying conversion rate used for streaming in different markets as well as by most labels on their communications. The method also secures that the same formula applies to all artists. In doing so, we grant that comparisons between artists from different periods make sense, unlike lists based on raw records totals. That’s what we call equivalent album sales (EAS), or simply CSPC units. If you are not familiar with this concept, it consists in retrieving sales figures from every format and weighting them on par with album sales. To solve these flaws, we introduced several years ago the Commensurate Sales to Popularity Concept (CSPC). Our home-made solution : the CSPC and equivalent album sales The latter are adding together apples and oranges by mixing distinct formats and different national streaming conversion methods. The first are given only on-request, sparsely for many artists, and relate to the US only. Most of these lists floating around online are either flat lists of RIAA certifications or a mere sum of all certifications from all countries. Today, the same lack of education on the matter continues to be a pain for accuracy lovers. For decades, marketing tricks from labels and lack of education from media led to various myths about the best selling artists of all-time getting repeated so often that the general public assumed it was true.
