Napster CEO Chris Gorog isn't so impressed with the Microsoft software his online music system uses.

In fact he reckons a catalogue of technical glitches in Microsoft's media software and devices made by music player manufacturers have done nothing but "hamper" his ability to compete with "it just works" Apple.

Speaking to Australian IT, Gorog complained: "There is no question that (Microsoft's) execution has been less than brilliant over the last 12 months."

He observes that Napster's success depends on Microsoft and that company's hardware partners, describing the partnerships as "more complex" than Apple's iPod and iTunes approach.

It appears the competing services are still at the entry-level age: "It's always been painful at the introduction of new technologies," he said.

Apple reached one billion song sales last week. Despite Apple's clear market lead, Gorog continues to sing the song of Redmond, saying the Microsoft system will prevail: "Ultimately, the consumer electronics giants are all going to come to this Windows Media party. This is really going to be the ubiquitous format."

Responding to recent rumours that it may happen, Gorog also for the first time conceded that Napster may seek a buyout.

"We will do a deal if and when we feel it's in our shareholders' interests," he said.
