At the end of the year, Apple likes to tally up all the singles and albums purchased by iTunes Store customers.; they call it iTunes Rewind.  The 2010 Rewind best-sellers are Train and Eminem for single of the year (“Hey, Soul Sister”) and album of the year (“Recovery”), respectively.  In addition to Train, the top ten best-selling singles include tracks from Katy Perry, Eminem (2), B.o.B, Taio Cruz (2), Usher, Ke$ha, and Lady Antebellum.  The top ten best-selling albums include records from artists Ke$ha, Ladies Gaga and Antebellum, Taylor Swift, Drake, Mumford & Sons, The Black Eyed Peas, Jack Johnson, and Sade.  Before you jump after the break to look at the top ten lists, make some predictions to test your wits; it shouldn’t be that hard to guess what two single Taio Cruz made uber-popular this year.

iTunes Rewind covers more than the music category.  Apple also tallies up the best-selling TV shows, movies, podcasts, audiobooks, and apps.  And yes, it is safe to assume that the app featuring unwieldy birds and idle, snorting green pigs took home the top prize of best-selling paid app.  Click here to browse all the Rewind charts.
