Stop annoying PopUp: To Play "...", stop playing on another device

Quite often I start playing music on a device while I stream music on the Mac.

In the past the Music simply stopped on the Mac, which was perfect for me.

Since a couple of months, when I come back to the Mac, there are two popups I need to close, stating:

"To Play "(Title)", stop playing on another device".

SOLUTION:

open the Terminal

paste the following:

defaults write com.apple.Music no-bouncing -bool TRUE

hit Enter, confirm the permission request in the popup window.

Done
