Why it matters: The 25-year wait from the song's release to its place at No. 1 is the longest in Billboard history. It also adds to Carey's personal chart records — the song is now her 19th No. 1 (the most among solo artists; and overall trailing only The Beatles' 20) and her 80th week at No. 1 (Rihanna is closest at 60). It's also the first holiday No. 1 since The Chipmunks' "The Chipmunk Song" in 1959.
