I have the same issue with a Series 1 and Watch OS5. This will be a little bit of a rant.
Pretty much from day 1 of buying a new car earlier in the year with Carplay when I would plug in my iPhone it would start playing music. There is no way to turn autoplay off, it's pretty irritating to have to reach up and turn off music I didn't ask for every time I plug in my phone.
When I bought my watch it then also would have the song I didn't want to play on my watch face so that would have to be minimized.
Jumping to WatchOS5, that stupid icon all the time. Yesterday I plug in to my car so I can use the very useful feature to make a hands free call driving down the freeway, song starts autoplaying so I have to turn it off, song on watch face to minimize and of course the stupid icon which blocks the Do Not Disturb or Airplane mode icons which are pretty important to remind me when I go off and on Airplane mode all day long. (I fly for a living)
There is a way to supposably keep the song from coming up on watch face:
- Press the Crown on your Apple Watch to invoke the app launcher.
- Launch the Settings app.
- Tap General.
- Tap Wake Screen.
- Toggle off Auto-Launch Audio Apps.
Didn't work for me without and with a restart AND updating to 5.01 that @#$%^& icon still came back after installing. I hadn't touched the music since I got into my car earlier in the day. My car is in the driveway. The music app is closed on my phone.
My solution to fix the problem (and it did) is to remove every single song off my phone, everything.
So Apple ruined music for me with their in your face approach to music. No more music in my car or going on foot, I did put a few songs on my iPad so I can at least listen though a bluetooth speaker at home.
No more IOS or watch updates for me until I absolutely have to.
Hot tip for Apple- Not everyone's life revolves around listening to music.
And thank you for saving me almost $500 on a new Series 4 I planned to buy. I'll upgrade when the devices I have stop working (I'm still going strong with a late 2008 MacBook Pro thank you very much).
Rant Over.
