(Repeats, adding link to Billboard) Feb 22 (Reuters) - Madonna was named the biggest money maker in music in 2012 on Friday, with a world tour helping her take home up to $34.6 million and highlighting the earning power of live performances as the industry increasingly goes digital. The 54-year-old Material Girl topped Billboard Magazine's annual list of 40 top money makers for the second time after earning an estimated $32 million - 93.5 percent of her revenue - from her 88-date "MDNA" tour, 2012's biggest tour.

British songstress Adele won the Grammy for best pop solo performance on Sunday, the first award handed out during the main event on the music industry's biggest night of the year. She also gave a typically straight-talking answer when asked how she is feeling about the Oscars later this month, where she is nominated for best song for the theme tune to Bond movie "Skyfall," admitting she was nervous. The 24-year-old singer, who swept the board with six Grammys at last year's awards show, took the pop performance prize for a live rendition of her hit "Set Fire to the Rain."
