Apple Music is now streaming. The subscription music service has gone live as part of iOS 8.4, which is now available for iPhones and iPads. Though the update includes a small number of other changes, it's primarily about the release of Apple Music. The service is available inside of a redesigned version of iOS' Music app, which has been changed to almost entirely focus on the streaming service. It's a big moment for Apple, which was once the biggest name in digital music and is now trying to reclaim its title. Alongside the release of Apple Music, Apple's digital radio station, Beats 1, is going live as well. It's supposed to kick off at 12PM ET. There should be new Pharrell and an Eminem interview.
