Dolby is considering taking legal action against K-Fed for violating copyright law by using his 1983 smash, "She Blinded Me With Science," in the song reports MTVnews.

"You can't just take a very well-known piece of music and add your own vitriolic rap over the top of it and get away with it," Dolby told MTV News on Wednesday (April 5). "If anybody's going to sing nasty lyrics over my music, it's going to be me."

"America's Most Hated," which Federline recently debuted on his MySpace page, actually samples Mobb Deep's "Got It Twisted," which sampled "She Blinded Me With Science."

"Mobb Deep came to me and asked for a license," said Dolby, who was paid a fee and receives royalties for Mobb Deep's song.

"We issue licenses all the time, for movies and TV shows and so on. I was aware of the Mobb Deep one, but I certainly never
issued a license to Kevin Federline."
