Calvin Harris named top hitmaker in Music Week

Pop star Calvin Harris was the most successful songwriter in the UK singles chart in 2011, according to research from trade magazine Music Week.

Harris wrote Rihanna's number one track We Found Love as well as having hits of his own with Bounce and Feel So Close.

He also gained a songwriting credit on US star Chris Brown's song Yeah 3X after complaining that it copied his 2009 single I'm Not Alone.

The Smeezingtons, who wrote for Bruno Mars and Cee Lo, were in second place.

Singer-songwriter Adele was in third place thanks to her enormous success last year, with fellow chart star Ed Sheeran in fourth.

Music Week head of business analysis Paul Williams said: "2011 was a great year for British songwriters, reflected by high positions on this chart for Calvin Harris, Adele and Ed Sheeran."

British writers also enjoyed a good year in the US, he added, with We Found Love spending 10 weeks at the top of the US singles chart, while Adele had three chart-topping songs in America.

Norwegian duo Stargate were in fifth place on the list after penning tracks for Rihanna, Jennifer Lopez, Wiz Khalifa and Alexis Jordan, while their songwriting partner Ester Dean was in sixth.

Lady Gaga was seventh in the top ten, followed by Claude Kelly, who co-wrote tracks including Jessie J's Price Tag.

In ninth was Welsh composer Paul Mealor, who wrote the Military Wives' Christmas number one Wherever You Are.

American writer-producer Dr Luke, who won Billboard's songwriter of the year in 2010 and 2011, rounded off in the list in tenth position.
