Mariah Carey performs at the 81st Annual Rockefeller Center Christmas Tree Lighting Pre-Tape at Rockefeller Center on Dec. 3, 2013 in New York City. 

Carey's 1994 carol surges to No. 7 and Autry makes his first Hot 100 appearance.

Holiday music continues to storm the Billboard Hot 100 chart, as nine seasonal songs debut, re-enter or reach new peaks on the latest list (dated Dec. 15).

As previously reportedMariah Carey leads the pack, as her holiday staple "All I Want for Christmas Is You" leaps from No. 14 to No. 7, hitting a new peak, after it reached the top 10 (No. 9) for the first time last year. The song surges with 30.4 million radio audience impressions (up 11 percent), 28.5 million U.S. streams (up 29 percent), 15,000 downloads sold (up 28 percent) in the tracking week, according to Nielsen Music. With the ascent, Carey achieves her highest rank since "Obsessed" reached No. 7 in 2009.

"Christmas" concurrently leads Billboard's Holiday 100 chart, which ranks the top holiday hits of all eras using the same methodology as the Hot 100, blending streaming, airplay and sales data.

Also as previously noted, Wham!'s "Last Christmas," from 1984, makes its first visit to the Hot 100's top 40, rising 43-34, and the late Dean Martin appears on the chart for the first time in nearly 50 years, as "Let It Snow, Let It Snow, Let It Snow" storms in at No. 41.

Late country legend Gene Autry earns his first-ever Hot 100 entry, as "Rudolph the Red-Nosed Reindeer" has a very shiny debut at No. 36. Autry (who died at age 91 in 1998) released the track in 1949, nine years before the Hot 100 launched, and it finally debuts, gaining by 40 percent to 18.5 million U.S. streams. (Per chart rules put in place this decade, older songs, like Autry's, Carey's, Wham!'s and Martin's, are eligible to chart on the Hot 100 if showing multi-metric gains and ranking in the top 50.)

Plus, Autry's Rudolph the Red Nosed Reindeer and Other Christmas Classics leaps 68-49 on the Billboard 200, up 41 percent to 17,000 equivalent album units.

Here is a rundown of all the holiday songs on the Dec. 15-dated Hot 100:

Rank, Title, Artist
No. 7, "All I Want for Christmas Is You," Mariah Carey (up from No. 14)
No. 16, "It's the Most Wonderful Time of the Year," Andy Williams (up from No. 21)
No. 21, "Rockin' Around the Christmas Tree," Brenda Lee (up from No. 23)
No. 22, "A Holly Jolly Christmas," Burl Ives (up from No. 26)
No. 26, "Jingle Bell Rock," Bobby Helms (up from No. 22)
No. 29, "The Christmas Song (Merry Christmas to You)," Nat King Cole (up from No. 39)
No. 34, "Last Christmas," Wham! (up from No. 43)
No. 36, "Rudolph the Red-Nosed Reindeer," Gene Autry (debut)
No. 41, "Let It Snow, Let It Snow, Let It Snow," Dean Martin (debut)

Andy Williams' "It's the Most Wonderful Time of the year" enters the Hot 100's top 20 for the first time, rising 21-16. The track earns Williams (who passed away at age 84 in 2012) his ninth top 20 hit and first since 1971, when "(Where Do I Begin) Love Story" reached No. 9. Among his 40 total Hot 100 hits, he earned four top 10s.

Also reaching new peaks: Burl Ives' "A Holly Jolly Christmas," Bobby Helms' "Jingle Bell Rock" and Nat King Cole's "The Christmas Song (Merry Christmas to You)." Ives and Cole sport their highest Hot 100 ranks since 1962 and 1964, respectively, while Helms continues climbing with his top-charted title.
