'FIFTEEN,' 12-10 HIKE!: Taylor Swift tallies her fourth top 10 on Billboard's Pop Songs radio airplay chart, as "Fifteen" lifts 12-10.

With her latest feat, Swift doubles her lead as the country-crossover artist with the most top 10s in the Pop Songs chart's 17-year history.

Here is a look at the select three country artists (all female) to make multiple visits to the Pop Songs top 10:

Taylor Swift
No. 7, "Teardrops on My Guitar" (2008)
No. 1 (one week), "Love Story" (2009)
No. 2, "You Belong With Me" (2009)
No. 10 (to date), "Fifteen" (2010)

LeAnn Rimes
No. 4, "How Do I Live" (1997)
No. 8, "Can't Fight the Moonlight" (2002)

Shania Twain
No. 3, "You're Still the One" (1998)
No. 5, "That Don't Impress Me Much" (1999)

Swift could add a fifth top 10 as soon as next week. "Two Is Better Than One," by Boys Like Girls featuring Swift, pushes 14-13 on Pop Songs.

Country makes additional further inroads on Adult Pop Songs, where Lady Antebellum's "Need You Now" debuts at No. 40. The track joins "Fifteen" (26-22) and Carrie Underwood's "Cowboy Casanova" (24-23) as the third track on the list that previously reached the top 10 on Country Songs.

AT SEVENTEEN: In the latest "Uprising" update, Muse remains atop Alternative Songs for a 17th week. If the track can notch an 18th week at the summit, it will tie the mark for most frames spent at No. 1 established by Foo Fighters' "The Pretender" in 2007.

"Uprising" isn't the only entry in the upper reaches of Alternative Songs with noteworthy staying power. Weezer's "(If You're Wondering If I Want You To) I Want You To" holds at No. 3 for a second week after logging 12 frames at a No. 2 peak. If it can return to the runner-up spot for one more stanza, it will match Green Day's "Time of Your Life (Good Riddance)" in 1998 for most weeks spent peaking at No. 2.

Only one other song has totaled double-digit weeks peaking at No. 2 since Alternative Songs originated in 1988: Blink-182's "What's My Age Again?," which racked 11 weeks in second place in 1999.

ADULT ENTERTAINMENT: Jaheim earns his fourth No. 1 on Adult R&B (viewable at billboard.biz), as "Ain't Leavin' Without You" rises 2-1.

The New Jersey native, born Jaheim Hoagland, previously led with "Anything" (three weeks, 2002), "Fabulous" (two weeks, 2003) and "Never" (one week, 2008).

Since the Adult R&B chart launched in 1993, the only male artists with more No. 1s than Jaheim are Brian McKnight, Luther Vandross (six each) and Musiq Soulchild (five). Kenny "Babyface" Edmonds, Maxwell and R. Kelly have also each made four trips to the summit.

COMPLETE BEAT: Ke$ha arrives atop the Billboard 200 with her debut album, "Animal." With her maiden single "TiK ToK" having moved into the Hot 100 penthouse three weeks ago, Ke$ha is the first female artist to send her introductory album and song to No. 1 on the Billboard 200 and Hot 100, respectively, since Leona Lewis in 2008. What other women have achieved such double domination out-of-the box? For a detailed rundown encompassing the more than 50-year archives of each survey, check out Chart Beat tomorrow.
