However, Spotify recommends running watchOS 7.1 or later for the best experience. To get offline playlists, you have to have an Apple Watch Series 3 or later, running at least watchOS 6.
This update also brings Siri support for Spotify on the watch using voice commands such as, “Hey Siri, play my Discover Weekly Playlist on Spotify.” (You just have to remember to add the “on Spotify” part.) All a user has to do is select the music or podcast they want to listen to, press the three dots, and then hit “Download to Apple Watch.” A little green arrow will then appear next to the fully downloaded content. In its official blog, Spotify said it’s rolling out offline playlists starting today. You can finally, finally download playlists, albums, and podcasts onto the watch for offline use. Spotify users with Apple Watches can breathe a sigh of relief.
