Roxio's Napster And Software Divisions To Exceed Second Quarter Guidance

Proposed Sale of Software Division to Sonic Solutions on Track

Santa Clara, California - (September 20, 2004) - Roxio®, a division of Sonic Solutions® (NASDAQ: SNIC), the leader in digital media software, today announced that it expects to exceed prior guidance for both its software and Napster divisions for the second fiscal quarter of 2005.

Napster revenues are expected to be approximately $9 million, ahead of the company's previously issued guidance of $8 million. Roxio software division revenues are expected to be approximately $18 million compared to guidance of $17 million. Roxio expects that combined EPS loss for the quarter will be narrower than current analyst consensus estimates.

"The strength of Napster's results reflects increasing traction in the online music market and a favorable mix toward subscribers. We are excited by numerous near-term business catalysts for Napster including the upcoming consumer launch of, and device support for, the 'Napster To Go' portable subscription service, along with the full implementation of our partnership with Best Buy," said Chris Gorog, Chairman and CEO. "Our proposed sale of the Roxio software division is on track to close in the fourth calendar quarter, pending Roxio stockholder approval and customary regulatory reviews. The successful completion of this proposed transaction will significantly strengthen Napster's balance sheet and eliminate the need for additional funding for the foreseeable future."
