Apple has seeded the third beta version of its upcoming iOS 8.4 update, with most of the new tweaks centered around the music app as the company gears up to launch its Beats-driven streaming service next month.

The current update includes a streamlined look for the Music app, with a new mini-player, a new-look, easier-to-get-to iTunes Radio section and a wider range of results in Music Search. In addition, the Now Playing screen opens as a full screen when you hit play as opposed to just appearing as a bar at the bottom. There's also a more prominent toggle switch to let you turn off the Cloud and just show the music on your phone. (See screengrabs at 9to5Mac.com.)

The Beat(s) Goes On

The update (officially iOS 8.4 beta 3) also includes some fixes associated with earlier betas. Other known issues to be worked out in future updates -- according to release notes for developers -- include stability issues with iTunes Radio, Siri's inability to control the radio function and various minor display issues like ads showing up on top of navigation buttons.

Unsurprisingly, there are no traces of a streaming service included in the latest beta release.

As previously reported, Apple is expected to launch its premium-only, Beats-based subscription service this year at the company's 26th-annual WWDC event, scheduled for June 8-12 in San Francisco, at the Moscone West. The conference will also host the Apple Design Awards, as well as a 350 STEM-related scholarships available.
