Plus, Wham!'s "Last Christmas" hits a new high and Jonas Brothers' "Like It's Christmas" debuts.
Like a shiny ornament placed in its familiar, special spot atop a tree, Mariah Carey's "All I Want For Christmas Is You" rules the Holiday 100, for a 36th of the chart's 41 total weeks since the list launched in 2011; it has topped the tally for 21 consecutive weeks, dating to the start of the 2015-16 holiday season.
The only other Holiday 100 No. 1s to date: Justin Bieber's "Mistletoe," for a week in the 2011-12 holiday season; Pentatonix's "Little Drummer Boy" (one, 2013-14) and "Mary, Did You Know?" (two, 2014-15); and, Ariana Grande's "Santa Tell Me" (one, 2014-15).
