MacStories has compiled a list of all the new Apple Music playlists added:
What we found was over 250 playlists each designed to fit a mood or activity that use animated cover art with simple line drawings to set them apart from Apple’s other playlist. Although they were announced as Siri playlists during the event on Monday, anyone with an Apple Music subscription can view and play the new playlists in the Music app like any other playlist in the service’s collection.
