U.K. collecting society the MCPS-PRS Alliance has revealed figures for the most popular songs on licensed Web Sites last year, including YouTube, iTunes and Bebo, with Syco Music artist Leona Lewis' "Bleeding Love" coming out on top.

The MCPS-PRS Alliance analyzed 60 million downloads and streams of music in order to pay royalties to its 60,000 members of composers and songwriters.

The quantity of performances was boosted by fan videos, often of people performing the songs to camera. The craze for group dance videos also contributed to the results.

Leona Lewis' "Bleeding Love" made up 6% of all analysed performances, with "Crank That (Soulja Boy)" by Soulja Boy the second most popular track. "Apologize" by Timbaland featuring One Republic was at No. 3 followed by "Umbrella" by Rihanna featuring Jay-Z and Sean Kingston's "Beautiful Girl" at No. 5.

"The trend for posting self-made videos is driving the number of performances on the Web Sites we license," says MCPS-PRS managing director of broadcast and online Andrew Shaw in a statement.

Shaw adds, "As more and more music is consumed online, we need to continually develop increasingly sophisticated tracking systems in order to ensure that the songwriter and creator community is sustained, enabling a continued future for music."
