Rhythm Nation 1814 produced No. 1 Hot 100 singles across three different calendar years

Janet Jackson’s Rhythm Nation 1814 accomplished something no album had done before — it spun off Billboard Hot 100 No. 1 singles in three different calendar years (1989, 1990, and 1991). That kind of sustained chart dominance is almost unheard of, and it cemented the record as one of the most commercially potent pop albums of its era.
