iOSi 17.4.1 Bluetooth Problem: strange

Scenario: when I when I start my 2018 Honda Ridgeline, the Bluetooth in my phone automatically connects to my audio system and begins to play the current song on the Music app. This is fine, however if I’m listening to a book on tape and begin to play that on my phone, it stops the song from playing and begins playing the book on tape, also fine. The problem occurs, when I stop the book on tape from playing. What happens is the song on the Music app begins to play again, unbidden I should add, and at about 10 times normal speed. I have to bring the music app up and actually flick away to make it. Strange, I must say.
