Analyst firm Merrill Lynch now expects Apple to sell 20 million iPods this year.

Analyst Steve Milunovich predicts 4.5 million sales in this quarter alone, according to Apple Insider.

The analyst also explained that despite many reports, he doesn't see Napster's new On The Go service grabbing market share from Apple.

Merrill Lynch rates Apple a 'Buy' with a $51 per share target price.

In related news, a series of Apple insider transactions have recently been reported through US financial regulators. These include stock sales by Apple director Arthur Levinson and senior vice president Phil Schiller in February. Senior vice presidents Jonathan Rubinstein, Sina Tamaddon, Tim Cook, Nancy Heinen and Bertrand Serlet made extensive stock sales in January.
