104FM is one of the most-popular radio stations in Dublin, but its new ad has Lady Gaga fans screeching.
It shows a woman's body under a canvas with blood seeping out and the title "When you play great music back-to-back someone is gong to get hurt."
There is blood on the wall behind the body, and a woman's leg is protruding from under the canvas.
Beside the dead body is a sign reading "Britney Spears Lady Gaga," a play on Britney Spears and her last name.
Outraged fans have begun deluging the site complaining about the ad.
"This entire campaign is bloodbath in more ways than one. If I were the client I would start freaking out right about now as ad revenue began to fall and listeners switched to stations that did not machete their listeners," says one comment.
"This is disgraceful and completely out of order," said another.
The ad agency responsible is called Bloom and based in Dublin.
It seems the ad has had a major impact on the web, with some sites running headlines about Lady Gaga being dead, not realizing it is a radio station advertisement.
