Apple got me this time. The biggest company in the world is very good at selling a piece of hardware (in this case the Apple Watch) and then linking it to an essential piece of software (Apple Music).
The watch can’t play any other music offline apart from Apple Music. I only want to play music on my watch when I am offline on a run or in the gym.
I had to quit my previous music subscription (Tidal) to join Apple Music, to go to the gym and listen with my watch!
