Stop ringing and singing me, yo

Eminem's publishing companies filed a lawsuit in an effort to stop his songs from being used as cell phone ring tones.

They are seeking a court order to prohibit five companies from selling Eminem ring tones on the Internet.

Lawyers for Eminem said they also plan to sue karaoke companies that sell Eminem songs without getting the proper licenses.

"This is a big business. We're talking hundreds of thousands of dollars a year," said Howard Hertz, a lawyer representing the plaintiffs.
