Wheres 2Pac, Foreigner, etc.?
A lot of older superstars are not on the list because the record industry has grown over the last forty years. Thus, a number one album in 1997 will most likely sell more than a number one album in 1957 did. On the other hand, some older albums benefit from replacement sales. For example, I’ve bought three different configurations of Thriller and Purple Rain in my lifetime. I’ve also bought compact disks of many other albums that I used to own on vinyl; not that there’s anything wrong with vinyl.
