They must be independent. The Beatles albums actually average out to more than 10 songs each and, as you point out, 1 million albums would be more than 5 million songs.
The real question is whether a box set is included as just one album. If so then that will make a big impact on the numbers. One box set is 14 albums and 256 songs. If they are just recorded as one album then that the number of reported albums won't accurately reflect what has been bought.
Probably not. If people still buy music created by classical, baroque, and romantic era composers; why should any world-famous group not continue to see sales?
Ha! That's how I got my Beatles albums![]()
Bingo, who remembers the c*** music of 300 years ago? Anyone who saw the film Amadeus knows how tormented Salieri was to see Mozart's music become more and more popular while his faded out.![]()
There is still good/great music being created today, and no one will recall Justin Beiber in 200 years except historians.
