Spotify - Volume control

Questions & Suggestions
4

Looks like that would need to be explored by someone with a Spotify account, I’m afraid.

I did spend a couple of minutes downloading the app, but probably because I have no account, it crashed when I ran this:

tell application "Spotify"
	set lngVol to sound volume
	set sound volume to 50
	set lngVol to sound volume
end tell

Perhaps a note to Spotify support ?
