– Revenue from digital music matched that from physical albums and discs for the first time in 2014, a global industry body said Tuesday.

The International Federation of the Phonographic Industry's annual report said digital and physical sales each accounted for 46 percent of the $14.97 billion in global music revenues. Income from performance rights and synchronization revenue made up the rest.

The old-fashioned vinyl format has had a renaissance and now accounts for 2 percent of revenues.

Total revenue was down 0.4 percent from 2013, but the group said the overall picture for the industry was positive.

The federation said the rise of subscription music services was driving digital growth, and there was "substantial untapped potential for growth" in the paid-for streaming sector.

"Music companies are charting a path to sustainable year-on-year growth," said IFPI Chief Executive Frances Moore.

But she said that the industry was missing out on revenue because some platforms including YouTube are exempt from copyright laws applied to music-streaming services like Spotify — despite having many more users.
