PlayGenre

Starts playing all the songs in your LMS library that match the specified genre on the specified/assumed/elicited player.

If you have a very large library and tens of thousands of songs in the requested genre, queuing them up in LMS may take longer than you might expect in which case Alexa will ask you to be patient. If you have no songs in the requested genre, she'll inform you thusly.

Invocation options (choose based on grammar-fit):

Alexa, [ open / start / launch ] MediaServer
Alexa, [ ask / tell ] MediaServer [ to / for ] …
