The first booth I encounter is a dude demonstrating a new vocal auto-tuning technology. He explains to onlookers that the singer riffing into the mic, whose voice is being “auto-corrected,” might accidentally ‘discover’ a melody she didn’t even mean to sing. And ta-da! Hit song by accident. Imagine that! I want to raise my hand and ask, what about an idea? Doesn’t a song need an idea?
