As previously reported, Eminem and Rihanna rule the Billboard Hot 100 for a third week with "The Monster." Who else receives holiday gifts in the form of notable chart moves this week?

-- Katy Perry: Katy Perry's new single "Dark Horse," featuring Juicy J, gallops 22-14 on the Hot 100 with Digital Gainer honors. "Horse" trots 17-7 on Hot Digital Songs (111,000 downloads sold, up 87%, according to Nielsen SoundScan), 26-16 on Streaming Songs (2.7 million U.S. streams, up 39%, according to Nielsen BDS) and 48-31 on Hot 100 Airplay (37 million in all-format audience, up 50%, according to BDS).

With its Hot 100 move, "Horse" matches the No. 14 peak of Perry's prior single from her "PRISM" album, "Unconditionally." On Dance Club Songs, "Unconditionally" becomes Perry's record-extending 12th consecutive No. 1, a run that began with "Waking Up in Vegas" in 2009.

-- Florida Georgia Line: The twosome scores its landmark fourth career-opening No. 1 promoted single on Country Airplay, as "Stay" rises 3-1. (It ranks at No. 30 on the Hot 100.) With its Country Airplay coronation, FGL ties fellow twosome Brooks & Dunn (1991-92) as the only acts to begin with four leaders in the chart's nearly 24-year history. (The latter pair peaked at No. 6 with its fifth entry, "Lost & Found," so FGL could break the record with another No. 1 on its next try.) "Stay" follows the Country Airplay toppers "Cruise," "Get Your Shine On" and "Round Here."

-- John Mayer, Perry: Perry, meanwhile, re-enters the Hot 100 at No. 48 with John Mayer on "Who You Love," following the Dec. 17 premiere of the duet's video. The song had first logged a week at No. 80 two weeks ago. With 50% of its Hot 100 chart points from streams, it debuts on Streaming Songs at No. 25 (2 million, up 601%). Most of the rest of the song's points total (44%) are from sales, with the track returning to Hot Digital Songs at No. 45 (35,000, up 237%).

-- Tessanne Chin: Crowned winner of the fifth season of NBC's "The Voice" (Dec. 17), she debuts on the Hot 100 with covers of Whitney Houston's "I Have Nothing" (No. 51) and the Beatles' "Let It Be" (No. 76), the latter a duet with her "Voice" coach, Adam Levine. The songs arrive with sales of 79,000 and 56,000, respectively.

-- Brantley Gilbert: After the digital track and its accompanying video were released simultaneously on Dec. 16, "Bottoms Up" begins at No. 1 on Country Digital Songs (63,000). The song becomes Gilbert's first leader on the chart, where his previous best peak was No. 13 with "You Don't Know Her Like I Do" two years ago. The Georgia native achieved his prior best digital sales week when his breakthrough hit "Country Must Be Country Wide" sold 29,000 (Jan. 14, 2012). On the Hot 100, "Bottoms" bows at No. 58.

-- U2: As "Ordinary Love" lifts 13-9 on Triple A, U2 breaks the record for the most top 10s in the chart's almost 18-year archives. Now with 21 top 10s, the group passes Dave Matthews Band (20). Coldplay ranks third with 18, followed by Jack Johnson (16) and John Mayer (15).

-- Tiesto: In his debut week, he matches the peak of his previous single, "Take Me," on Dance/Electronic Songs with his latest, the unconventional-for-him, pop-stylized "Red Lights" (No. 19). "Lights" features an uncredited male vocalist and guitars, reminiscent of Avicii's "Hey Brother" and "Wake Me Up!"

Tiesto's chart action is powered heavily by digital sales, with the track entering Dance/Electronic Digital Songs at No. 9 (14,000). Of 15 chart hits on that list, this is the Dutch DJ's second top 10, following "Feel It," which reached No. 7 in 2010.

-- Gene Autry: The late legend and Country Music Hall of Famer tops the Country Streaming Songs chart with "Rudolph the Red-Nosed Reindeer," more than 60 years after its original release. It jingles 2-1 with 1.1 million U.S. streams, according to BDS.

Autry, who passed away in 1998, first released the song for the 1949 holiday season.
