The Billboard Hot 100:
As previously reported,  Adele's "Set Fire to the Rain" spends a second week atop the Hot 100, just holding off a furious push from Kelly Clarkson's "Stronger (What Doesn't Kill You)," which bounds 8-2. Who else displays strength on this week's chart?
-- Gym Class Heroes: Let's get to the bottom of how the cheeky "Ass Back Home," featuring Neon Hitch, ends up cracking the top 20 (24-19): it jumps 19-14 on Hot Digital Songs (87,000 downloads sold, up 7%, according to Nielsen SoundScan) and 34-29 on Hot 100 Airplay (41 million audience impressions, up 15%, per Nielsen BDS).
-- Gotye: "Somebody That I Used to Know," featuring Kimbra, jumps 50-31 on the Hot 100, 36-18 on Hot Digital Songs (72,000, up 29%) and 7-5 on Rock Songs. On Jan. 29, the singer tweeted his approval of a "clever" YouTube cover of the song by Right the Stars  featuring Karmina that incorporates a portion of the Police's "King of Pain." The original's official version (above) has racked 57 million YouTube views since last July.
-- The Wanted: the British vocal group's "Glad You Came" reaches the Hot 100's top 40 (64-40), roaring 70-33 on Hot 100 Airplay (50,000, up 73%) and arriving as the highest debut on Hot 100 Airplay at No. 61 (22 million, up 36%).
-- Colbie Caillat: In its 24th week on the Hot 100, "Brighter Than the Sun" reaches a new peak (48-47). The song has received prominent placing of late in TV promos for the Drew Barrymore/John Krasinski film "Big Miracle," opening in theaters Friday (Feb. 3). After peaking at No. 2 on Adult Top 40, the cut lifts 35-34 on Mainstream Top 40 and 6-4 on Adult Contemporary.
-- LMFAO: "Sorry for Party Rocking," the follow-up to two Hot 100 No. 1s ("Sexy and I Know It" at No. 7 and "Party Rock Anthem" at No. 20) and the title cut from the pair's second album, bows at No. 92. The song concurrently becomes the duo's fourth top 10 on Dance/Electronic Digital Songs, where it lifts 12-9.
The Billboard 200:
As earlier reported,  Adele's "21" rests at No. 1 on the Billboard 200 for an 18th week, fending off seven debuts in the top 10. It seems likely that "21" will maintain the No. 1 slot next week too, with Lana Del Rey's "Born to Die" aiming for a No. 2 debut. But, before we get to next week's chart, let's take a closer look at a few interesting moves on the Billboard 200 -- outside the top 10:
-- The Doors: The 40th anniversary edition of the 1971 album streeted last week and it returns to the list at No. 78 (6,000) for the first time since early 1972. It was the last studio album recorded with the band's former singer Jim Morrison, who died on July 3, 1971 -- a couple months after "L.A. Woman" was released. The album spawned a pair of top 40 hits on the Billboard Hot 100 for the band, as "Love Her Madly" reached No. 11 and "Riders on the Storm" climbed to No. 14. The latter single debuted on the tally on July 3 -- the day Morrison passed.
-- Tony Bennett: PBS' Great Performances series debuted its "Duets II" special on Jan. 27, featuring behind-the-scenes recording footage of the icon with the album's many guests. The icon's original "Duets: An American Classic" album is up by 48% (reentering at No. 128) while "Duets II" zooms 88-28 (up 162%). The two albums are among Bennett's three best-selling albums since SoundScan began tracking data in 1991. "Duets: An American Classic" is his biggest (with 1.8 million), followed by "MTV Unplugged" (809,000) and "Duets II" (751,000).
-- Wilco: The band's new iTunes-exclusive "Sessions" bows at No. 54 (8,000) while a specially priced (and promoted) "Whole Love" reenters with 3,000 (up by 52%). The new "iTunes Session" set boasts a cover of Nick Lowe's "Cruel to Be Kind" (featuring Lowe himself!). "Cruel" was the set's biggest selling download last week, shifting 2,000 copies. (It was also Wilco's best seller of the entire week -- across all of their available songs.)
-- Blake Shelton: The Target-exclusive deluxe edition of his "Red River Blue" album -- which came with his single "Footloose" and a T-shirt -- was offered for $15.99. In turn, it's up by 85% and zips 92-48 on the tally. So far, the album has sold 532,000 copies -- making it his biggest selling album since 2004 "Blake Shelton's Barn & Grill." The latter has racked 801,000 in sales thus far.
