StreamAlbumNewest
Streams the newest album in your collection that's credited to a specified artist to the Echo to which you issue the command (i.e. the Echo is the audio sink for LMS). If you omit the artist name it will be elicited by Alexa. 'New' is not defined by date of addition to your library but rather by the year tag for the album.
Touchscreen buttons for prev/next/pause appear on Echos with displays when the screen is tapped. The skill's invocation name can be omitted for transport commands such as play/pause/stop/next/previous/startover while streaming. Audio will auto-pause the moment you say 'Alexa'.
When streaming starts, a pseudo-player with 'Alexa-XXXXX' in its name will appear in the LMS GUI — one for each currently-streaming Echo. Note that the time/track/index shown in LMS/iPeng will not match the stream due to aggressive buffering by the Echo. If you change anything from the GUI, simply say 'Alexa, resume' to re-align and clear the buffer. You cannot query now-playing data for an Echo or synchronize it, also due to buffering.
Invocation options (choose based on grammar-fit):
Alexa, [ open / start / launch ] MediaServer
Alexa, [ ask / tell ] MediaServer [ to / for ] …
