Music could make Apple a billion dollars this year, said Merrill Lynch analyst Steven Milunovich in a note to clients yesterday.

Discussing Apple's market-leading iPods, he said: "The success of the iPod demonstrates Apple's tech know-how and strong brand and could make the company relevant again," Dow Jones reports.

Milunovich estimates Apple's iPod will yield $1 billion this year, and anticipates revenues could double to $2 billion by 2006.

"We're more optimistic in believing that iPod is not just a one-hit wonder that will be knocked off," he said.
