On Monday, Apple seeded the second beta of iOS 8.4 with a revamped Music app that will be integrated into the Apple/Beats premium streaming service, MacRumors, among other geek sites, reported. The update arrives two weeks after the seeding of the first iOS 8.4 beta, and six weeks before the June 8 kickoff of the WWDC , when we expect the Apple/Beats service to be unveiled.

Here’s the MacRumors breakdown, which is also visualized in the above video (to the soundtrack of Imagine Dragons’ “It’s Time):

The new Music app has a revamped design that shows pictures of artists in the Artists view and offers personalized playlists. It includes a new MiniPlayer, a redesigned look for "Now Playing," global search capabilities that makes it easier to search within the Music app, and a streamlined design for iTunes Radio to bolster music discovery.

The first iOS 8.4 beta had a long list of bugs associated with the new Music app, and it's likely that the update fixes several of those issues to make the app more stable.

Missing music bug: Several users are reporting that installing iOS 8.4 beta 2 caused them to lose all of their music installed on their devices. Those who have lost music are not able to reinstall it by syncing via iTunes, but going to Preference --> Music --> and turning on "Show All Music" has solved the problem for some users with missing music.

Trending Search: When searching for a song on iTunes Radio using the new global search feature, a list of trending searches is displayed (see screenshot above left).

Fixes: According to the release notes, Apple has addressed a number of issues from the first beta, including resolving a crashing Music app when used with CarPlay, adding search back to the iPad version of the App Store, and fixing problems with MFi GPS accessory support. The company has, however, yet to address most of the many Music apps bugs documented in the first beta, as they remain listed in the release notes for the new beta.
