The good news is Apple Music works with Carplay.
Yes it does...I used CarPlay, Apple Music and my iPhone the past couple days in a Kia rental. Worked great!
Wouldn't it be possible to use an Apple TV 4 plugged into your Bose Soundtouch 300 to then use AirPlay 2 to play Apple Music from your iPhone?

You wouldn't need to turn on the TV. Just turn on the Apple TV and Bose. Plug the Apple TV into the soundbar. Seems like a good, simple solution for people who seem to think it's the end of the world because they can't use Air Play with their Bose Soundtouch 300.
