iTunes released their best-selling figures of 2010 and Train's "Hey, Soul Sister" was the biggest single according to The Hollywood Reporter.
The song, which was released in Aug 2009, was eventually covered on "Glee" by Darren Criss and the fictional Dalton Academy Warblers group on the show. Though some people on the web grew tired of hearing the song and started a petition blog called "Stop Advertising From Pulling A Train."
Rounding out the top five singles, according to Apple's figures, are a few collaborations including Katy Perry and Snoop Dogg's "California Gurls," Eminem and Rihanna's "Love the Way You Lie," B.o.B and Hayley Williams of Paramore's "Airplanes," and Taio Cruz's "Dynamite."
Meanwhile Eminem's "Recovery" was dubbed the best-selling album of 2010. Ke$ha came in second with her album "Animal," Lady Gaga ends up in third place with "The Fame," Lady Antebellum's "Need You Now" is in fourth, and Taylor Swift's "Speak Now" takes fifth.
