The change also brings more direct UI cues for users to navigate through the Radio tab, with a "Listen Now" button under the currently airing show and the less-hidden option to "Explore Beats 1."
Before the update, the Radio tab had a simple, unchanging Beats 1 logo with a "Listen Now" button that users could tap to jump directly into whatever was airing at the moment without exactly knowing what that would be.
The app also gave users the opportunity to explore more information by delving into a secondary menu that listed live shows and upcoming hosts and interviews on Apple's radio channel. Some might not have even known about the auxiliary menu, since there was no UI hint to its existence - tapping anywhere on the Beats 1 logo launched it. Now "Explore Beats 1" should help guide more users to the scheduling menu.
Anyone on iOS 9.2.1 -- or the beta iOS 9.3 seed -- should see the Beats 1 update, but a quick multitasking-enabled close of Apple Music will help it show up if you aren't seeing it. As of writing, no similar update was seen on the Mac version of Apple Music.
