As 2011 draws to a close, Apple has once again decided to take a look back at some of the top content on iTunes this year.

Dubbed iTunes Rewind, the roundup lists, among other content, the top-selling movies, apps, books, and music during the year, as well as Apple staff's top picks in each category.

Apple doesn't provide sales figures in Rewind, and it's worth noting that its lists are based solely on iTunes sales. But it still provides solid insight into what we were interested in this year.

Read on to find out which shows, movies, apps, and more were the top winners on iTunes in 2011:

Apps

For the second year in a row, Angry Birds was the top-selling paid iPhone application, followed by Fruit Ninja and Angry Birds Seasons. Angry Birds HD was the top paid iPad app.

Given Facebook's success, it's no wonder the social network's application was the top free app in the App Store. Pandora Radio and Words with Friends Free edition came in second and third place, respectively.

Instagram earned top honors for best iPhone app this year, as voted by Apple staff.

Photo-effect application Snapseed was tapped as the best iPad app of the year.

Music

Adele's "Rolling in the Deep" was the year's top-selling song on iTunes, while LMFAO's "Party Rock Anthem" and "Firework" by Katy Perry followed closely behind.

Given the success of her single and "21" album, which took the top spot in sales, as well, Apple staff gave Adele "Artist of the Year" honors.

The Foo Fighters' "Wasting Light" was voted the top album this year by Apple staff.

"Pumped Up Kicks" by Foster the People was voted the best song.

Apple gave "Harry Potter and the Deathly Hallows--Part 2" the "Best Blockbuster" nod this year.
