It is a ranking that aims to see which albums retain popularity the longest. The red and blue album sold more than a million sets during the 1970s. Another million sets were sold since it was put into CD form in 1993. Compared to today's bestsellers which can sell 5 million or more, a million sets does not appear to be a remarkable achievement. Taking into consideration the value of money and market size however, the same million is worth 10 times more.
People are more concerned about how they are ranked during the first week of the release.
The promotion prior to the release is thought to be crucial in attaining a good ranking. The Beatles' albums, however, are genuinely attractive because of their content. After all, it has continued to sell for more than 25 years. On the other hand, however, we try to add value by including commentaries that weren't there in the original albums. We position it as the most important album in the world and ask CD shops to place it in the best possible location.
