If apple made is easier to get what their shows are and when they air. But I have mostly given up on Beats1 and just listen again to my collection and my normal webradios from around the world.
I thought it was easy enough, in the app, tap on the beats 1 image, you get the schedule and list of shows. If you tap on a show in the 'Featured Shows', you get playlists for each show, which gives you an idea of what is going to be played....
