MGM Studios and online file-sharing service Grokster are preparing for a music copyright fight before the U.S. Supreme Court, Rolling Stone reported.

The nation's highest court next week will hear arguments on MGM's suit against the Internet file-sharing service and the court's decision will set the tone for U.S. copyright law on the Internet, the magazine said.

The Recording Industry Association of America took a tough stance on sharing music files.

"Any business that is based entirely on copyright infringement should be held accountable," association President Cary Sherman said.

Grokster will argue there are legal uses for its file-sharing application, one favored by independent artists to get their music before fans.

Even NASA uses the technology to distribute large files used by the U.S. space program, Grokster will argue.

Should MGM win, file-sharing sites such as Grokster and eDonkey may be forced to shut down, the magazine reported.
