British singer Adele has became the first artist to secure three milestones on the iTunes music chart, scoring 2011's top-selling single, top-selling album and being named the iTunes Artist of the Year, the music company said on Thursday. The 23-year-old singer's single “Rolling in the Deep” beat stiff competition from Katy Perry, Bruno Mars, LMFAO and CeeLo Green in the top-selling songs category, while her album “21” was able to surpass records from Mumford & Sons, Lil Wayne, Coldplay and Kanye West and Jay-Z. The iTunes Rewind list highlights the year's most downloaded items from Apple Inc's iTunes stores but the company did not give sales figures. __
