How Long is my playlist in Apple Music Tahoe?

Bob, Change the playlist view settings (at least temporarily) to View > As Playlist and View > Show Status Bar. Then you will see the required information at the top left. (You might have to scroll the header away.) Example in screenshot.

You could script it and assign the script to a keyboard shortcut. Getting the duration of a playlist isn't too hard - this is clunky (I'm not a coder really) but it works OK.

tell application "Music"
	set thePlaylist to the name of the view of front browser window
	set theTime to the time of the playlist thePlaylist
	display dialog theTime
end tell

The duration is displayed in dd:hh:mm:ss

If you want to have a go at it then the following link explains how to create a Service script. You can then add that Service to a keyboard shortcut.

Getting the duration of a selected bunch of songs is a bit more complicated, but I'm sure it's doable. I've not updated to Tahoe yet in hope.

Hi Bob,

Thanks! It's kind of clumsy but at least it shows the playlist time down to the second.

Glad it helped. Enjoy the music!
