Mariah Carey‘s “All I Want for Christmas Is You” showed up right on schedule again this year. Carey posted her annual “It’s time” video as Halloween rolled into November 1, and the 2026 edition opens with her singing “Hermit.” That’s a song by Chick, the mid-’90s alt-rock side project she didn’t talk about publicly until her 2020 memoir. Then she turns up on top of a decorated Christmas tree to say the magic words, and the song kicks in.

That starts roughly eight weeks of hearing it everywhere, and my patience for it usually runs out around Thanksgiving. It will almost certainly return to #1 on the Billboard Hot 100 in December, as it has every holiday season since 2019, and this year it has an all-time record to win back. Nostalgia explains some of that staying power. Plenty of the rest was written into the song in 1994, and you can see it in the official sheet music.

A 1994 album cut that needed streaming

The song couldn’t even chart when it came out. It was ineligible for the Hot 100 in 1994 because no physical copies were on sale, according to Guinness World Records, and it didn’t enter the chart until January 2000, spending one week at #83. On-demand services like Spotify started counting toward the Hot 100 in 2012, and from then on it came back every December. It cracked the top 10 for the first time in December 2017 and reached #1 on the chart dated December 21, 2019, 25 years after its release.

It has topped the chart every holiday season since, piling up 22 total weeks at #1, four of them last season. That was the all-time record until Ella Langley’s “Choosin’ Texas” logged its 23rd week on top in September, prompting NPR’s Stephen Thompson to joke that the two songs might trade the crown every year forever. Langley’s hit logged its 26th week on top on the chart dated November 7, so Carey’s song needs at least five more this season to retake the record.

What the official score shows

The official Hal Leonard easy piano arrangement on MuseScore covers the free-time intro and the first verse in 43 bars of G major. The opening is marked “Freely,” with the left hand holding whole notes under the melody, and the arrangement doesn’t settle into strict time until bar 17, where the tempo marking jumps to 150 beats per minute. On the record, that’s the slow, floating opening before the band comes in.

Bar 5 is a plain C major chord. Two bars later the arrangement swaps it for E-flat major, a chord borrowed from G minor that shades the next two bars darker. The B7 in bar 10 is a secondary dominant pulling toward E minor in bar 11, and from there the bass slides down a half step at a time to D, by way of a Cm6 voiced over E-flat in bar 12. Both the intro and the verse wrap up with an E7(#5) resolving to Am7, which sets up a D7-to-G cadence around the circle of fifths.

Adam Ragusea’s 2014 analysis for Slate counted at least 13 distinct chords across the full song, a much bigger palette than the three or four he says carry most rock and pop. He singled out the minor iv chord with an added sixth, the Cm6 in bar 12 here, as the song’s most Christmassy sound, and he heard the same chord in Irving Berlin’s “White Christmas.”

Bars 17 and 18 add one more old trick. As the tempo arrives, the chords run G, Em, C and D, the I-vi-IV-V changes that carried ’50s doo-wop. Every one of these moves was in common use by the early ’60s, and that’s the era Carey and co-writer Walter Afanasieff were reaching for.

A Wall of Sound built on sequencers

Afanasieff told Nile Rodgers on Apple Music 1 that they wanted something simple and old-school, “kind of Phil Spector-y.” In a 2019 interview with Variety, he said he worked out boogie-woogie chords at the piano while Carey built the verse melody. Back home in San Francisco, he “played every single instrumental on the track,” using synths and sequencers in place of a live band. So the vintage Wall of Sound on the record is mostly one producer and a sequencer rig doing an impression of 1963. Carey has told the writing story differently over the years, though the two split the credit evenly.

Whether the song owed anything to another writer ended up in court in 2023, when country singer Andy Stone, who performs as Vince Vance, and co-writer Troy Powers sued Carey and Afanasieff for $20 million, claiming Carey’s song copied their 1989 tune of the same name. In March 2025, U.S. District Judge Mónica Ramírez Almadani granted summary judgment to Carey and Afanasieff after siding with defense experts who said the shared elements were common Christmas clichés that predated both songs. In the Ninth Circuit, stock material like that gets filtered out under the extrinsic test before a court compares whatever protectable expression is left. The judge also sanctioned the plaintiffs, and Rolling Stone reported in December that Stone’s lawyers had been ordered to pay Carey $92,300.

The soundtrack to the shopping season

The song acts as a relentless soundtrack to the storm of commercialism that drives the holiday season, and the song itself rakes in millions each year. Billboard estimated Carey made about $2.7 million to $3.3 million from the song’s recording and publishing revenue in 2022, and the law firm Manatt, Phelps & Phillips figures it has earned around $103 million worldwide since 1994, NBC News reported. Songwriters and publishers also get paid when a song plays in public spaces like restaurants and retail stores, so the shops that loop it all season feed the writers’ side of the ledger too. Even the November 1 ritual has turned into ad space. Carey’s 2025 “It’s time” video doubled as a Sephora ad, complete with a #SephoraPartner tag.

Some stores start their holiday playlists as early as October, and the people who hear them most are the ones working the registers. Clinical psychologist Linda Blair told Sky News in 2017 that store employees who can’t tune the music out become “unable to focus on anything else,” CBS News reported.

Playing it yourself

For anyone who wants to play it at a family get-together (maybe you aren’t sick of the song yet), the easy arrangement is a quick learn. The left hand holds whole notes through the intro and settles into steady quarter notes once the verse gets going, and the flats cluster in the E-flat bars and the Cm6. Set a metronome to 150 before you reach bar 17, since coming out of free time into a strict tempo is the easiest spot in the arrangement to rush.
