The service is now available to use in 100 locations across the globe, including the UK and the USA.
Apple first announced Apple Music at its annual Worldwide Developer Conference earlier this month.
To access Apple Music, users will first need to upgrade their phones to the latest iOS 8.4 software. That’s now live and available to download, as of 4pm BST, June 30.
At 5pm BST, June 30, Apple’s Beats 1 radio station will begin its 24/7 broadcast, starting with ex-Radio 1 DJ Zane Lowe.
Apple Music is available for users on iOS, watchOS, Mac, and Windows. An Android version is in the works, but that’s pegged for an autumn release.
The service costs $9.99/£9.99 per month to use, although Apple is offering everyone a free three-month trial to get a taste of the company’s fledgling streaming efforts. You can also upgrade to the family plan for 6 simultaneous audio streams, but that'll cost $14.99/£14.99 per month instead.
