Washington, April 25: The student who doctored Beyonce Knowles' track out of tune has apologised for the prank, saying it "got out of hand".
Matthew Zeghibe had altered the tunes of a song the R&B queen performed on live TV last November, making her vocals sound ear splitting.
The record found its way on the Internet and became popular amongst fans, bloggers and shock jock Howard Stern, who played the track on his U. S. radio show.
Following the storm, the singer's father Mathew had insisted the leaked "board mix" had been fiddled with.
Art student Zeghibe finally stepped forward to confess his misdoing, which he claimed was just for fun.
