The way we consume music has changed dramatically. What used to be album sales have quickly, and sometimes dramatically, turned into streaming audio. Services like iTunes bridged a gap between physical and digital sales, but we’re well past that, now. Streaming is in, and monthly subscriptions have supplanted our out-of-pocket spend for albums. To reflect actual song plays, Billboard will now start to appreciate streaming statistics in their reports. It’s the first big change since Billboard started using SoundScan metrics.
