There are a couple things from SpotMenu I saw after poking around that might help interfacing with the Spotify client more smoothly; specially around getting the player state.

Referencing the the Spotify app directly

• https://developer.apple.com/documentation/scriptingbridge/sbapplication
• https://github.com/kmikiy/SpotMenu/blob/master/MusicPlayer/Player/Spotify/Spotify.swift#L24

Using notification center for updates (push)

• https://developer.apple.com/documentation/foundation/distributednotificationcenter
• https://github.com/kmikiy/SpotMenu/blob/master/MusicPlayer/Global.swift#L14
• https://github.com/kmikiy/SpotMenu/tree/1a53424ea1802b88bf83db52f1044b65fb677642/MusicPlayer/Player/Spotify#L84

I think with this approach the AppleScript timed polling could be eliminated and even more performance would be found since it won't have to poll while the Spotify isn't active or playing.
