The elusive chanteuse scored a No. 1 on the Billboard Hot 100 in the 1990s, the 2000s, the 2010s and now, the 2020s.
The Billboard Hot 100 data combines radio airplay, sales and streaming data, and the latter measure likely boosted Carey’s song to the top.
The record is also one of few songs with at least 72.2 million streams in one week, Billboard reported.
A few other artists have topped the chart in three different decades, including Stevie Wonder, Elton John, Madonna and Usher, but Carey gets the four-decade crown — and with what’s now the highest-charting holiday song of all time.
