with a single album, michael jackson sold more than 100 million copies of thriller, so in total it is logically and significantly more than 330 million records sold. I estimate Michael Jackson's sales at more than 700 million
In the Beatles era, people didn't buy albums. They bought singles, and a lot of the most famous Beatles songs were only released as singles. They sold 1.6 BILLION singles in just the United States alone. Albums only became a thing well after the Beatles started, and it was largely due to them.
