I am aiming for the mac app store, and I used script editor to run this script, it is basic but opens the music app and plays songs at the specified playback points from the specified Playlist

tell application "Music" set thePlaylist to playlist "Playlist Plunderer" if (count of tracks of thePlaylist) < 1 then display dialog "Playlist does not have any tracks." return end if repeat with theTrack in tracks of thePlaylist set trackDuration to duration of theTrack -- Play track at specified percentages repeat with p in {0.15, 0.5, 0.75} play theTrack delay 1 set player position to trackDuration * p delay 4 stop end repeat end repeat end tell
