Apple today releasing the iOS 8.4 version, the fourth update to iOS 8 introduced last year. First introduced to selected developers in April 2014, iOS 8.4 includes a newly revamped Music app and Apple's long-awaited on-demand streaming music service, Apple Music.
iOS 8.4 is available immediately as an over-the-air download, and the new Apple Music service is located within the Music app. Apple Music will be available immediately after iOS 8.4 is installed, while the Beats 1 radio service will kick off at 9:00 a.m. Pacific Time.
Along with Apple Music, today's iOS 8.4 update includes a complete overhaul of the built-in Music app. It incorporates Apple Music and it features a new design that shows pictures of artists in the Artists view and a new MiniPlayer with a revamped "Now Playing" look. There are personalized playlists, global search capabilities that make it easier to search within the Music app, and a streamlined design for the radio feature to bolster music discovery.
Other minor changes in iOS 8.4 include the relocation of audiobooks from the Music app to the iBooks app, consolidating all books, print, and audio into one convenient spot, and a new Audiobooks for CarPlay app, giving drivers a standalone app dedicated to playing their audiobooks.
