It took a pop singer to question why people get music for a song. Earlier this summer, Taylor Swift publicly shamed Apple for planning to offer a free trial of its music service: "We don't ask you for free iPhones. Please don't ask us to provide you with our music for no compensation." Her essay was remarkable not just because it challenged a giant corporation, but because it was a searing reminder of the anemic state of the music industry. Apple isn't the only guilty party.
