CSPC: The Beatles Popularity Analysis
Remaining Long Format Part 4 – EPs
Seeing the likes Please Please Me, With the Beatles and Beatles For Sale around 6 million copies sold to date in their original format make them look much weaker than their latter material. The reality is different through. Those albums have not only generated sales of various other similar local releases, they also contributed immensely into millions of EP sales.
As per CSPC rules, an EP is weighted as half of an album. The only exception is Magical Mystery Tour EP which was a double one, thus getting back a full one album equivalent weighting. This makes perfect sense as this EP was exactly released instead of the album in some countries back in the day, including in the UK.
