Full Length related record Sales
It sounds fairly logical to add together weighted sales of one era – studio album, physical singles, downloads, streams – to get the full picture of an album’s popularity. For older releases though, they also generate sales of various live, music videos and compilation albums.
All those packaging-only records do not create value, they exploit the value originating from the parent studio album of each of its tracks instead. Inevitably, when such compilations are issued, this downgrades catalog sales of the original LP. Thus, to perfectly gauge the worth of these releases, we need to re-assign sales proportionally to its contribution of all the compilations which feature its songs. The following table explains this method.
Remaining Long Format – Part 1
How to understand this table? If you check for example the The Singles Collection compilation line, those figures mean it sold 375,000 units worldwide. The second statistics column means all versions of all the songs included on this package add for 766,000 equivalent album sales from streams of all types.
The second part on the right of the table shows how many equivalent streams are coming from each original album, plus the share it represents on the overall package. Thus, streaming figures tell us songs from Demon Days are responsible for 52% of The Singles Collection tracklist attractiveness, which means it generated 195,000 of its 375,000 album sales and so on for the other records.
All remix and video records released by the band were themed after a specific studio album, thus most of their respective sales belong to the relative album set. The last two items, iTunes Sessions and The Singles Collection were career spanning which concludes on their appeal being spread among their first three albums, with the main attraction comes from Demon Days hits.
