MediaServerDuration
Tells you the duration of the current song — plus that of the entire playlist — for the specified/assumed/elicited player.
The command usually works fine with Spotify/Qobuz/Deezer/Tidal but not with internet radio stations as they don't provide duration data.
Invocation options (choose based on grammar-fit):
Alexa, [ open / start / launch ] MediaServer
Alexa, [ ask / tell ] MediaServer [ to / for ] …
