Carly Rae Jepsen's "Call Me Maybe" this week pushes ahead of "We Are Young" by fun. featuring Janelle Monae to become the second best-selling song of 2012. That was no small feat: "We Are Young" has sold 5,515,000 copies so far this year. "Call Me Maybe" is now a hair ahead of it with sales of 5,531,000. "Somebody That I Used To Know" by Gotye featuring Kimbra continues to hold the lead for the year-to-date, with sales of 6,300,000.

In the very unlikely event that nobody bought another copy of any of these songs for the rest of the year, 2012 would still go down as the first year in digital history that three songs sold 5.5 million copies in a calendar year. Last year, just one song topped that threshold: Adele's "Rolling In The Deep" (5,813,000).

As you can see, "Call Me Maybe" is just 769K copies behind "Somebody That I Used To Know" as the year's best-selling hit. Can it possibly catch it before the year is over? I don't think so. "Call Me Maybe" sold 98K copies this week, but the

This week, for the first time since it was released in February 2011, Adele's 21 does not rank among the top 10 albums on The Billboard 200. It drops from #8 to #12, ending (at least for now) a 78-week run in the top 10. 21 is one of only five albums to log 78 or more weeks in the top 10 since 1963, when Billboard merged its separate stereo and mono charts into one comprehensive listing. The others are The Sound Of Music soundtrack (109 weeks), Bruce Springsteen's Born In The U.S.A. (84 weeks), Michael Jackson's Thriller (78 weeks) and Def Leppard's Hysteria (78 weeks).

Much has happened in the pop world since 21 was released. Amy Winehouse (whose success paved the way for Adele) died, as did Whitney Houston, Donna Summer, Robin Gibb and Adam Yauch of Beastie Boys. Justin Bieber and Chris Brown both released two #1 albums. One Direction and 2Chainz debuted. Lionel Richie made an improbable comeback. Katy Perry tied Michael Jackson's record for most #1 hits from one album. American Idol crowned two more winners, Scotty McCreery and Phillip Phillips. The Voice debuted and stole some of Idol's thunder. Maroon 5 got its second wind.

First-week sales for Taylor Swift's "We Are Never Ever Getting Back Together" were as unambiguous as its title. The song sold 623K copies, which is the second-highest one-week total in digital history. It trails only Flo Rida's "Right Round," which sold 636K in its first week in February 2009.

This enables Swift to set new records for the largest one-week digital sales tally by a female artist (eclipsing Ke$ha's "TiK ToK," which sold 610K in December 2009); by a country artist (eclipsing Swift's own "Love Story," which sold 360K in December 2008); and by any artist in 2012 (eclipsing "Somebody That I Used To Know" by Gotye featuring Kimbra, which sold 542K in the week ending April 15).

"We Are Never Ever…" is the first single from Swift's fourth studio album, Red, which is due Oct. 22. Swift's last studio album, Speak Now, sold 1,047,000 copies in its first week of release in October 2010.

Flo Rida's "Whistle" jumps to #1 on the Hot 100, displacing Carly Rae Jepsen's "Call Me Maybe," which was #1 for nine weeks. Female solo artists and male/female collabos have had a near-lock on the #1 spot this year. "Whistle" is only the second #1 hit so far this year on which a woman wasn't at least featured. The only other all-male #1 of 2012 is LMFAO's "Sexy And I Know It," which hit #1 in January.

The last time a male solo artist who was strictly solo hit #1 was in February 2011, when Wiz Khalifa's "Black And Yellow" grabbed the top spot for one week.
