Billboard Hot 100, October 15, 2011

1.(2) Someone Like You - Adele

Adele returns to #1 for a second week at the top with "Someone Like You." The song is #1 in sales, #2 in airplay. It's currently #3 at top 40 radio, where it's the fastest gaining song (it should be #2 tomorrow). This is the third #1 hit to spend nonconsecutive weeks at #1 this year, following Bruno Mars' "Grenade" and last week's #1, Maroon 5 & Xtina's "Moves Like Jagger."

5.(4) Party Rock Anthem - LMFAO (feat. Lauren Bennett & GoonRock)
6.(10) Sexy and I Know It - LMFAO

"Party Rock Anthem" may have sounded like a one-hit wonder's #1 hit, but alas, LMFAO has a second hit, "Sexy and I Know It," up four places to #6 this week.

7.(NEW) Strange Clouds - B.o.B (feat. Lil Wayne)

B.o.B is back with the first single from his second album, which is this week's highest Hot 100 debut and B.o.B's fourth top 10 hit.

9.(16) We Found Love - Rihanna (feat. Calvin Harris)

Last week Rihanna was in the top 10 with her fifth top 40 hit from Loud, "Cheers (Drink to That)." This week, she's there with the first single from her upcoming sixth album, Talk That Talk. Notably, "We Found Love" is Rihanna's 20th top 10 hit, a feat she's achieved in just over 6 years, which is a record for a solo artist. Madonna held the record previously, having amassed her first 20 top 10 hits in just under 7 years. Mariah Carey did so in about 10 years. Among groups, The Beatles far surpass all of them, having amassed their first 20 top 10 hits in just 2 and a half years. "We Found Love" is this week's airplay gainer.

21.(22) Rolling in the Deep - Adele

Just wanted to acknowledge that this single is still "rolling" around the top 40, up a notch to #21 in its 39th week on the Hot 100.

28.(NEW) It Will Rain - Bruno Mars

Bruno Mars scores his 8th top 40 hit with It Will Rain, the single from the upcoming soundtrack to Breaking Dawn Part I, the movie Twilight fans can't wait to sink their teeth into this fall.

30.(38) Mr. Know It All - Kelly Clarkson

Kelly Clarkson may yet make a hit out of "Mr. Know It All." After an initial debut at #18 fueled by first-week sales, the single has had trouble catching on at radio, but it doesn't seem to be going away. It's currently #18 at top 40, gaining but not moving.

35.(45) Ni**as in Paris - Jay Z & Kanye West

Watch the Throne produces its third top 40 hit this week. It's released simultaneously with "Why I Love You (feat. Mr. Hudson)."
