I bought iLife 04 the other day and started experimenting with Garageband. It is a fascinating app. I have zero musical education and still, sitting in front of it, fiddling around with loops made me feel that maybe I can come up with something halfway decent.
But really, what is the probability that I will hit it big ? Come up with the next great sound ?
Honestly I think Apple is secretly using us musical amateurs for a great scientific experiment: the musical version of the Monkey Shakespeare Simulator.
Maybe GarageBand should be renamed to MobyMonkey.
