With Dangerous released in November 1991, Michael Jackson's career really sustained its high. The album entered the Billboard 200 album chart at number 1 and sold over 32 million copies worldwide in the space of 17 years. The RIAA certified Dangerous 7x platinum for shipping 7 million copies in the United States. Although Dangerous is definitely part of Jackson's quartet of aforementioned classic albums and shows off a diverse range of styles, the multi-platinum, number one album is sometimes overlooked.
