NEW YORK (AP) - It may be 2012, but it's a repeat of 2011 for Adele: Once again, she has the year's top-selling album on iTunes. Her "21," which recently passed the 10 million mark in sales, topped the list even though it was released at the top of 2011. It remained popular this year, particularly after she nabbed six Grammys in February. In the world of apps, "Angry Birds Space" was king of the top-paid iPhone and iPad apps, while those looking for freebies made YouTube the top iPhone app and Skype the most popular iPad app. Elsewhere, the top-selling movie was "The Hunger Games"; the best-selling TV show was an episode of "The Walking Dead" from season three; and the top TV series purchased for a season and a season's pass was "Downton Abbey," season two.
