Quick reminder:

Madonna’s first album “Madonna” would be considered an EP according to today’s standards (it came with only 8 tracks).

Lady Gaga’s 24 million units sold also include digital downloads, which did not exist between 1983-1987.

In other words, with less material in the market and with a lot more limitation when it comes to music format, Madonna sold more than double the amount of albums Gaga has sold in the same period of time.
