As reported yesterday on Billboard. com , Ke$ha  maintains her perch atop the Billboard Hot 100 for a second week with "TiK ToK" while setting the record for most single-week downloads by a female artist (610,000).
The prior female mark was set by Lady Gaga 's "Just Dance" (419,000) in the same holiday frame last year. Gaga, who holds at No. 3 on the Hot 100 with "Bad Romance," surpasses that sum as well with her "Romance" moving 445,000 this week.
Each title among the top 40 on the Digital Songs chart posts a gain -- all more than doubling last week's take -- in what is traditionally the strongest download sales week of the year. "Tik Tok" makes the most impressive jump, improving by 389,000 units to earn Digital Gainer honors.
Iyaz 's "Replay" jumps 4-2 to reach a new peak on the Hot 100. The song also resides at No. 2 on the Radio Songs and Digital Songs charts. Former No. 1 "Fireflies" by Owl City  lifts 5-4, while recent chart-topper "Empire State of Mind" by Jay-Z  + Alicia Keys  dips 2-5.
Moving up a slot each are Jason Derulo 's "Whatcha Say" (7-6) and Jay Sean 's "Down" (8-7). Sean also helps break a three-week streak of no titles moving into the top 10 as "Do You Remember," featuring Sean Paul & Lil Jon, rises 14-10. With that jump, Sean becomes the first male act since Chingy (with "Right Thurr" and Holidae Inn") in November 2003 to simultaneously appear in the Hot 100 top 10 with his first two charting singles.
Also moving into the top 10 is a retuning favorite, Miley Cyrus ' "Party in the U.S.A." (19-8). You would have to chalk this surge up to youthful Christmas week download exuberance as "Party" shifts 285,000 downloads, up 362%. The track, which peaked at No. 2 in late summer, was last in the top 10 six weeks ago. With "Party's" return to the upper tier, each of the top eight tracks on the Hot 100 has peaked at either No. 1 or No. 2. Rounding out our top 10 overview is "Sexy Chick" by David Guetta  featuring Akon , which slides 6-9.
Taylor Swift 's "You Belong With Me" is the chart's Airplay Gainer with an increase of 7 million listener impressions, 78% of which come form Adult Contemporary stations, many of which transition to normal programming following extended runs playing Christmas selections.
Also making big moves on the list due to digital sales is Justin Bieber  who sees two songs make identical 30-position jumps: "One Time" (47-17) and "One Less Lonely Girl" (60-30). The former track establishes a new peak position with its climb, surpassing a No. 20 rank achieved in November. The chart's biggest jump (80-45) goes to Jesse McCartney's "Body Language."
Selena Gomez  enjoys some holiday download benefits as she and her accompanying band The Scene have the Hot Shot Debut at No. 39 with "Naturally." The title jumps 65-34 on Digital Songs. They also re-enter the Hot 100 at No. 92 with "Falling Down."
Also new to the list are Young Money featuring Gucci Mane 's "Steady Mobbin'" at No. 48, "Hillbilly Bone" by Blake Shelton featuring Trace Adkins at No. 65, Eminem's "Music Box" at No. 82 and "American Honey" by Lady Antebellum at No. 97.
