Streaming music service Apple Music has 38 million paid subscribers, up from 36 million in February, the company said on Monday.

Apple is competing with Amazon.com, Google and others as streaming music becomes the dominant form of paid music consumption. Apple's number compares to 71 million premium subscribers at the end of 2017 at industry leader Spotify, which plans to list shares in the coming weeks on the New York Stock Exchange.

Eddy Cue, senior vice president of internet software and services, disclosed the most recent subscriber number for Apple Music at the South by Southwest festival in Austin, Texas.

Amazon Music Unlimited has 16 million paying subscribers, and Pandora Media Inc has 5.48 million total subscribers. Google does not release paid subscriber numbers for its service, Google Play Music.

Apple, Spotify, Google and other services charge $9.99 a month for music. Amazon offers its service to members who already pay for its Prime membership for $7.99 per month.
