I have a marathon tomorrow and I want to listen to an mp3 file that a DJ friend of mine made and sent to me as I run it.
Apple Music
So far, I have tried to import it into Apple Music on a computer, create a playlist and sync that playlist to my phone, which I was then hoping to sync to my Apple Watch.
Unfortunately I get errors about something called Cloud Music Library, and that I need to enable it, but when I enable it, the file I imported immediately gets deleted. I cannot click and drag this file or the playlist it sits in to my iPhone to get it to sync with the setting on or off.
Spotify
Spotify has a Local Files mode, which can enable playlists to be created to have audio files like mine sync with the iPhone and play from it.
However when I select the "Download to Apple Watch" option for the playlist with this file in it, it shows as completed on the phone, but the watch fails the download every time until it crashes. I do not believe the Apple Watch actually supports this.
This feels like it should be so so so simple. How do I play an audio file directly on my apple watch?
