Back in the ’90s, when the Walkman and CDs reigned, the industry combined basic sales data from the Billboard charts with two primary methods of song research: “Call Outs,” where stations played song hooks over the phone and record their responses; and “Auditorium” research, where a group of people react to song hooks as they are played live. In a pre-Internet age, it was about the best you could do.

And now, in 2013, an age of social networks, big data, and smartphones, surely terrestrial radio has developed a more nuanced methodology to find out what songs people really want to hear, right?

Not so much.
