Music opens by itself when using bluetooth / airplay Amplifier..
Whenever I connect to my external Bluetooth audio source (Powernode 2i) and play something Catalina decides that it needs to open Music.app - regardless of the audio source. It could be YouTube, even Slack audio notifications make it open!
This is really irritating since I don't use, nor wish to use Music. If I quit Music then the next time the computer plays a sound (from any app) Music opens itself again. c'mon really?
I have noticed that while Music is running, pushing Play etc on the Powernode 2i amp actually controls the Music app, skip track etc. I don't think the Powernode 2i is telling Catalina to open Music though. I suspect its something to do with Airplay getting excited and launching Music, ready for me to drink my dose of Apple Kool-aid.
Music is hijacking my experience with audio on my machine. This warrants a look by Apple - why does Music have its hooks into the audio bluetooth / airplay subsystem. It works fine without Music running!
Likewise there should be a Preference to replace Music with your own preferred Audio application, much like a default Browser or Mail client.
