By all rational accounts, Adele's 21, the singer's sophomore album released in January 2011, should have long faded from public consciousness. It's 2012. An album's half-life is about a week; two if you're Radiohead or a sugar-pop princess. But '21,' which recently surpassed the 10 million mark in sales, set another record, topping iTunes' best-selling albums of the year list for the second year in a row.

Taylor Swift and Mumford & Sons got the silver and bronze medals, but yes, '21' remains a behemoth and will probably be the music service's top-selling album through 2062, when it will be displaced by a Voltron-esque machine comprised of Katy Perry's daughter, the floating brain of Harry Styles and a previously lost strand of Psy's DNA found in amber and restored.

Carly Rae Jepsen's "Call Me Maybe" topped iTunes' best-selling songs, though Fun. and Flo Rida both have two spots each in the Top 10. Here's the full list:
