Jackson's 1982 album Thriller remains the world's best-selling album of all time, and four of his other solo studio albums are among the world's best-selling records: Off the Wall (1979), Bad (1987), Dangerous (1991) and HIStory (1995).
One of the few artists to have been inducted into the Rock and Roll Hall of Fame twice, his other achievements include multiple Guinness World Records, including one for "Most Successful Entertainer of All Time." He has won 13 Grammy Awards, charted 13 number one singles in his solo career—more than any other male artist in the Hot 100 era—and posted sales of over 750 million records worldwide, making him, according to the World Music Awards, the best selling solo artist of all time.
