(Cover) - EN Showbiz - Bruno Mars has the most watched music promo of 2011, according to muzu.tv.

Their statistics show that the singer's Grenade video was viewed the most on the music website.

The single was the second track to be released from this Bruno's album Doo-Wops and Hooligans. The short film shows the star dragging a piano around Los Angeles with a rope.

The 26-year-old revealed the theory behind the piece.

"The concept of the video is my struggle, to tell this girl I'd do anything for her, so I'm going as far as dragging a piano to get to her just so I can sing my heart out," Bruno explained.

His video for The Lazy Song also popped up in the chart at number eight.

Grenade was directed by Nabil Elderkin, who has also shot promos for Kanye West, The Black Eyed Peas, John Legend and Bon Iver.

Bruno's video was closely followed in the chart by that of Lady Gaga's song Born This Way, directed by Nick Knight.

It shows Lady Gaga as an alien, a skeleton in a tuxedo and dancing in leather underwear.

The only other artist to have two promos in the chart was British songstress Adele. Her Someone Like You video was placed at number seven and Rolling in the Deep appeared at number nine.

Other tracks in the chart were Jessie J's Price Tag and Rihanna's What's My Name. (C) Cover Media
