Napster said yeterday that it wouldn’t rule out a sale of the company after reporting that the subscriber base for its online music service had fallen 7 percent. “We do not have our heads in the sand regarding an M&A (merger and acquisition) transaction. We continue to receive a lot of interest in the company. We will always carefully weigh any valuation alternative against the opportunity and risk associated with continuing as a standalone company,” Napster CEO Chris Gorog told analysts on a conference call. Napster reported a net loss of $9.8 million for its first fiscal quarter. The company’s total paid subscriber base as of June 30 was 512,000, including 4,000 university-paid subscriptions.
