Beats 1, Apple's non-stop Internet radio station hosted by celebrity DJs, has made its first appearance in latest betas of iOS 8.4 and iOS 9 which are available to developers.
The Beats 1 interface appears unfinished with many features not active yet or performing erratically. Still, I was able to use the Music app on my iPad running iOS 9 Developer Preview to access a new Radio tab and get to Beats 1. I also browsed a list of stations and even streamed select ones and heard the promotional Beats 1 broadcast.
Here are my screenshots.
Apple seeded iOS 8.4 beta 4 to developers this afternoon. It is available immediately to those developers running iOS 8.4 beta 3 via Settings → General → Software Update. It is also now available as a download from Apple's redesigned Developer Portal.
The iOS 8.4 beta 4 release, which is build 12H4125a, comes nearly a month after iOS 8.4 beta 3. Apple announced at yesterday's WWDC keynote, that its new Apple Music streaming service was set to debut on June 30th. This means that we'll see the final version of iOS 8.4, in which Apple Music will officially arrive to the public, before the end of the month.
