(contactmusic.com) - Grace Kelly by Mika has been named as the top-selling download single of the year by iTunes.The Lebanese-born singer's second single outsold Rihanna's Umbrella - which went to number one in physical release charts across the world - and the Fray's How to Save a Life.But Mika was denied a single and album chart double by Amy Winehouse, whose Back to Black album claimed the number one spot.Life in Cartoon Motion was at number two, while the Arctic Monkeys' Favourite Worst Nightmare completed the top three.This year's iTunes charts correlate more closely with the official UK versions after download sales were included for the first time this year.The director of iTunes in Europe, Oliver Schusser, commented: "It's been a fantastic year for digital music, we now have more than six million songs on iTunes and I think the charts represent different flavours from different genres."It shows you how digital music has grown up."The director added: "There are a lot of people who don't download or pay for music, but technology will come again and redefine it and we're looking forward to it."iTunes top singles chart 20071 Grace Kelly - Mika2 Umbrella - Rihanna3 How to Save a Life - The Fray4 Ruby - Kaiser Chiefs5 Hey There Delilah - Plain White T's6 Stronger - Kanye West7 Foundations - Kate Nash8 Bleeding Love - Leona Lewis9 About You Now - Sugababes10 Shine - Take ThatiTunes top albums chart 20071 Back to Black - Amy Winehouse2 Life in Cartoon Motion - Mika3 Favourite Worst Nightmare - Arctic Monkeys 4 Version - Mark Ronson 5 Hand Built by Robots - Newton Faulkner 6 Beautiful World - Take That 7 Echoes - Foo Fighters 8 Yours Truly Angry Mob - Kaiser Chiefs 9 Eyes Open - Snow Patrol 10 Timbaland Presents - Timbaland
