Peter Suderman reviews "Genius," a new Apple feature:

You pick one song; Genius gives you the rest. Using complicated algorithms that match songs in your personal library by musical characteristics, data from millions of other iTunes users, and your own listening habits, it renders mixtaping an antiquity. No need to spend hours trying to figure out whether Right Said Fred's "I'm Too Sexy" is best followed by Hammer's "Too Legit To Quit" or C & C Music Factory's "Gonna Make Your Sweat." Let Apple's Genius feature make your musical decisions for you!

And Poulos gets a case of technophobia.
