As mentioned yesterday, a strong first week of digital sales (288,000, according to Nielsen SoundScan), propels Ke$ha's "We R Who We R" to a No. 1 debut on the Billboard Hot 100. But she's hardly the only artist making noise on the chart.

Taylor Swift, who has her own No. 1 glory on the Billboard 200 with "Speak Now," debuts 10 tracks from that album onto the Hot 100, led by "Sparks Fly" at No. 17. With holdover "Mine" falling 13-21, the singer has a total of 11 titles on the list, the most ever by a female artist.

With prior pre-album digital releases "Speak Now," "Back to December" and "Mean" having previously charted, every track from the 14-song standard edition of "Speak Now" has appeared on the Hot 100.

Relegated to No. 2 status on the Hot 100 and Digital Songs by Ke$ha's arrival is "Like a G6," by Far*East Movement featuring Cataracs & Dev. "Like a G6" topped the former list the past two weeks and had led Hot Digital Songs for three non-consecutive frames. It's possible that the song could return to the top of the Hot 100 next week.

Former No. 1 "Just the Way You Are," by Bruno Mars, falls 2-3 ahead of "Only Girl (In The World)" which also slips a spot to No. 4. "What's My Name," Rihanna's second single from "Loud," out Nov. 16, jumps 83-60 with Airplay Gainer honors. Without a digital single contributing to its ranking (it will next week), the title becomes the lowest-ranked Airplay Gainer winner since T.I.'s "Whatever You Like" (No. 71) on the chart dated Aug. 30, 2008, similarly a week prior to that single's digital release. T.I. took his track straight to No. 1 the following week, a move Rihanna could possibly mirror on our next chart, though a bump into the top 10 is more likely.

Back to the top 10, the songs from No. 6 to No. 9 all descend one rung on the ladder. Nelly's "Just A Dream' dips to No. 5, Usher featuring Pitbull's "DJ Got Us Fallin' In Love" lands at No. 6 and "Bottoms Up" by Try Songs retreats to No. 7. Katy Perry's "Teenage Dream" and Taio Cruz's "Dynamite" come in at No. 8 and No. 9, respectively.

Maintaining her standing at No. 10 is P!nk with "Raise Your Glass," one notch above 10-year old Willow, who wanders 78-11 in her second week on the list with "Whip My Hair." "Hair" sells 137,000 downloads in it its first week of availability.

"Monster" by Kanye West featuring Jay-Z, Rick Ross, Bon Iver and Nicki Minaj moves 79-18 after entering the Hot 100 and Hot Digital Songs last week with download sales accrued in a single day. Now with a full-week sales haul, the song rockets up the chart as the top Digital Gainer with 97,000 downloads (up 78,000 units).

While Taylor Swift makes a Glee Cast-like arrival with multiple debuts, the stars from the Fox series come in with just a single track from their "Rocky Horror Picture Show" episode, which aired on October 26. The cast's take on the classic "Time Warp" starts at No. 89. This is only the fourth week that the troupe has placed a single entry onto the chart, compared to 22 multiple-debut weeks.

Chris Brown debuts in the upper half of the list with "Yeah 3X" at No. 33. The pop/dance track, from Brown's upcoming fourth studio album, due first quarter 2011, moves 66,000 downloads in first week of release.

Also new to the list is "I Won't Let Go" by Rascal Flatts (No. 72), Kid Cudi's "Mr. Rager" (No. 77), "One in a Million" by Ne-Yo (No. 97) and Luke Bryan's "Someone Else Calling You Baby" (No. 100).
