Billboard has all of its year-end charts up now. Here's a rundown of the top 10 with peak positions of the year-end Hot 100:
1. Rolling in the Deep - Adele (#1, 7 weeks). 2011 belonged to Adele. No contest. "Rolling in the Deep" is the year's biggest hit, no surprise there. The song spent the most weeks at #1 on the Hot 100 and was a fixture on the chart all year long (it's still in the top 40). Her album, 21, was also the #1 album on the Billboard 200. Other #1 honors for Adele: Artist of the Year, Billboard 200 Artist, #1 Digital Song ("Rolling in the Deep"), #1 Digital Album (21), #1 Digital Albums Artist, #1 Adult Pop Song ("Rolling in the Deep").
2. Party Rock Anthem - LMFAO (feat. Lauren Bennett & GoonRock) (#1, 6 weeks). "Party Rock Anthem" was the summer hit of 2011. Like "Rolling in the Deep," this song stuck around a loooong time. "Party Rock Anthem" is #1 on Pop Songs.
3. Firework - Katy Perry (#1, 4 weeks). "Firework" was atop the Hot 100 when the 2011 calendar year began (Billboard's chart year runs from the beginning of December 2010 to the end of November 2011). It was her third #1 hit from Teenage Dream, following summer 2010's biggest hit "California Gurls" (the #4 hit of 2010) and fall #1 hit "Teenage Dream." Katy Perry was the year's #1 Radio Songs Artist, Digital Songs Artist, Pop Songs Artist and Adult Pop Songs Artist.
4. E.T. - Katy Perry (feat. Kanye West) (#1, 5 weeks). The fourth #1 hit from Katy Perry's Teenage Dream was also the fourth biggest hit of the year (the album's fifth #1 hit, "Last Friday Night (TGIF)" is just outside the top 10 at #14). The single version added a new rap from Kanye West, helping to propel the single's immense popularity last spring. Katy Perry is the only artist who appears more than once in the year-end top 10. For her effort, she is this year's #1 Hot 100 Artist. "E.T." is also the #1 Dance/Club Song and Perry is the #1 Dance/Club Songs Artist.
5. Give Me Everything - Pitbull (feat. Ne-Yo, Afrojack & Nayer) (#1, 1 week). Although this spent only 1 week at #1, it was a massive hit, especially at radio, where it was one of top 40's ubiquitous hits. In fact, the song is the year's #1 hit on Radio Songs.
6. Grenade - Bruno Mars (#1, 4 weeks). This, along with "Rolling in the Deep" and "Firework," is one of three Grammy Record of the Year nominees from 2011 in the year-end chart (a fourth from 2010 appears at #7 below). After he hit #1 with the sweet love song "Just the Way You Are," which is #15 on the year-end chart (penalized for having its chart run split between 2010 and 2011), he followed it up with this darker and even better pop hit.
7. Fuck You! - Cee Lo Green (#2). The F-word was big in 2011, forming the title of three top 5 hits from early this year. While Enrique Iglesias's "Tonight (I'm Fucking You)" is #16 and Pink's "Fuckin' Perfect" is #19, this Grammy nominee for Record of the Year was the year's biggest. Released in the summer of 2010, it slowly climbed the Hot 100 becoming a proper hit early this year.
8. Super Bass - Nicki Minaj (#3). Watching Nicki Minaj's career unfold this year was a magical thing. The buzz was deafening at the end of 2010, raising the stakes as to whether she'd live up to it. Initial singles failed to become big hits, but slowly but surely Minaj transformed into a star, with this single becoming far and away her biggest hit.
9. Moves Like Jagger - Maroon 5 (feat. Christina Aguilera) (#1, 5 weeks). The biggest late-year hit, "Moves Like Jagger" became Maroon 5's biggest hit in 7 years. Their 2004 smash, "This Love" was that year's fourth-biggest hit. Christina Aguilera appeared at #7 on the 1999 year-end chart with her #1 debut hit, "Genie in a Bottle."
10. Just Can't Get Enough - Black Eyed Peas (#3). Black Eyed Peas are no newcomers to the year-end top 10. In 2009, they had the year's biggest hit, "Boom Boom Pow," as well as the third-biggest hit, "I Gotta Feeling."
