Not surprising. How many people over the past 7 years have gone to the ITMS hoping to buy some Beatles music only to found out that it was surprisingly unavailable. A deeper inspection may have revealed the longstanding feud between Apple Computer and the Beatles' music label Apple Records.

But over the coming months, it becomes old news, and then people start searching for it.
