Songs in playlists are automatically favorited when I "pause" using spacebar - MacOS Sequoia

I have the same issue that came after I installed the Sequoia update.

I checked the keyboard shortcuts where the space bar is indicated as "Start playing or pause the selected song" in the help section and the "Controls" menu.

It must be a bug.

In Sequoia, the space bar can be used to press the default button on a dialog or window.

I didn't experience what you described but I would guess that the Favorite button would be the default when playing song in a playlist.

You can move to another button with the tab key, maybe that would move it to the play/pause button

Thank you for your reply.

You put me on the way for a solution.

In the keyboard settings, I have "Keyboard navigation" enabled. When disabled, the space bar works as intended in the Music app. When this setting is enabled, the space bar add/remove the song as favorite on first press and pause/play on 2nd and 3rd presses.

I guess I'll still leave this setting enabled as it's a faster way to interact with controls on screen without getting the mouse (using tab to move and space to select).

However, I also found some kind of workaround. When playing a title, if I click on an empty space of the app first, to deselect the song (i.e does not appear highlighted in red), then the space bar works as intended even with "Keyboard navigation" enabled.
