I recently deleted all my iTunes music since I listen to everything on Spotify or my podcast app (Downcast) now. I also updated to the iOS 11 public beta. Around the same time my car stopped playing anything via the USB cable, the car just said "no song" so I assumed it was an issue with the beta.

Literally yesterday I read about this "fix", so i re-downloaded the Music app and put just one song on it... yep it works!

Car players apparently assume you will only ever play music from the "default" library/app so when you connect it and it sees an empty library index, it assumes nothing can ever be played and just stops you there.

Very dumb.

First year BMW i3 recognizes Spotify and others just fine on current relase iOS and earlier as well, I think.

I'd conjecture it's a matter of how thoroughly apps got debugged by the vendors.
