Full Length related records Sales
It sounds fairly logical to add together weighted sales of one era – studio album, physical single, downloads, streams – to get the full picture of an album 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 one originated 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 how worth this latter is, we need to re-assign sales proportionally to its contribution of all compilations which feature its songs. The following table explains it all.
Remaining Long Format
How to understand this table? If you check for example Keeps Gettin’ Better compilation album line, those figures mean it sold 1,475,000 units worldwide. The second statistics column means all versions of all songs included on this package add for 418 million streaming plays on Spotify.
The second part at the right of the table shows how many streams are coming from each original album plus the share it represents on the overall package streams. Thus, streaming figures tell us Stripped songs are responsible for 37% of the Keeps Gettin’ Better tracklist attractiveness, which means it generated 544,000 of its 1,475,000 album sales and so on for the other records.
As previously mentioned, Mi Reflejo sales are split within’ the original album and the Orphan one. Many of those compilations / EPs / music videos came very early in the singer career thus largely representing the self-titled debut album. For the last two packages, this isn’t true anymore with Stripped and Back to Basics songs taking over the strength of their track lists.
