RIAA report confirms what we already know.

The 2018 midyear report underscores the continuing transition from physical and digital music sales to streaming services. Total revenues from recorded music in United States grew to $4.6 billion in retail for the first half of this year over of the same period last year—a 10% increase. Streaming music revenues grew 28% year-over-year to $3.4 billion, and paid subscriptions grew 33% to $2.5 billion. Finally, advertising-supported streaming services accounted for $369 million, a growth of 21%, and “digital and customized radio services”—including streaming from Internet radio stations, over-the-air radio stations, SiriusXM, and everything else for which SoundExchange is the collecting agency.
