LOS ANGELES (WO) - Adele has scored a chart double after her mega-hit album 21 was named the best-selling record on iTunes for a second year running. The Rolling In The Deep hitmaker was crowned the queen of iTunes last year when 21 was named the highest-selling record of 2011 by bosses of the online digital retailer. She has now repeated the feat for 2012. The album, which was released in January, 2011, has been named the year’s best-selling record ahead of Taylor Swift’s latest release Red, which hit charts in October.
