Apple rocks on with new GarageBand

At Macworld 2009 in San Francisco, Philip Schiller, Apple's senior vice president of marketing, demonstrates the company's updated GarageBand software. Now designed to help Mac users learn to play a musical instrument, GarageBand will let users download lessons from artists such as John Fogerty and Sting for $4.99. As a part of the lesson, artists give a bit of songs' back stories.
