itunestrack

#!/usr/bin/osascript
on run

Updated itunestrack

#!/usr/bin/osascript
on run
	set info to ""
	tell application "System Events"
		set num to count (every process whose name is "Music")
	end tell
	if num > 0 then
		tell application "Music"
			if player state is playing then
				set info to name of current track
			else
				set info to "Not Playing."
			end if
		end tell
	end if
	return info
end run

iTunes track didn't work.
Changed #(itunesartist) - #(itunestrack) in line 57 to #(./itunesartist) - #(./itunestrack)
Added this scripts to System Preferences > security & privacy > privacy > Accessibility
Added x rights to script: chmod +x itunesartist and chmod +x itunestrack

I saved my scripts inside /usr/local/bin, and added the scripts to accessibility and added x rights to the scripts, but didn't have to change line 57 from #(itunesartist) - #(itunestrack) to #(./itunesartist) - #(./itunestrack)

This config is very old with the current tmux version, ex: unbind-key
