The Rapid Rise of Digital Music

In 2013, global digital music revenues reached $5.9 billion, up from just $400 million in 2004. The lion's share of digital music revenue is still generated by paid downloads, although streaming services (subscription-based and ad-supported) quickly catch up. In 2013, global download revenues declined by 2.1 percent, while subscription-based and ad-supported streaming revenues grew 51.3 and 17.6 percent, respectively.
