Do you have a source for that claim? Because the store did not pop up until the same era as USB and Windows support.

Jobs cleverly made his pact with the record labels when iTunes worked only on Macs, which in 2002 had a personal-computing market share in the low single digits. Apple's humble position - before iTunes became compatible with Windows, expanding its potential market share to nearly all PCs - was a virtue. This made iTunes an experiment rather than a destructive paradigm shift. "I don't understand how Apple could ruin the record business in one year on Mac," said Doug Morris, the head of Universal Music, according to Appetite for Self-Destruction, a new book about the record industry's ills by Rolling Stone writer Steve Knopper. "Why shouldn't we try this?"
You could be right, but honestly I didn't want to take your position for fear of putting Steve on too high of a pedestal - for it would strain credulity for someone to have had his impact on six industries without the application of strategic thinking.
It would be truly god-like to have stumbled into it all via mediocrity.
