Wow! Had no idea. Yeah---releasing too many singles off an album is a great way to insure than ten years later, people looking at chart history say "man, they had a lot of stiffs and mid-charters."Despite Thriller breaking all the records as an album, that “multi-single” approach didn’t actually work for Michael either, outside of the US. Granted, the album spawned seven singles, but not all of them were successful in chart terms. With a couple of exceptions in other territories such as Canada and the Netherlands, the fourth, fifth and sixth singles all strayed outside the top 10 in Europe and in a lot of cases the top 40. In the UK, “Thriller” only barely scraped the top 10 and “Human Nature” scaled the dizzying heights of #162.
