Voice control, specifically requesting Model X to play a song, has changed dramatically. In the past, if I asked it to "play" a song, it quickly recognized even obscure songs and played them. Last night, while showing off to friends of course, the same thing resulted in a internet search and a list of albums and references, and if I selected "songs" it said "not found," even for common songs it used to play. I don't use the feature much, so the change could have happened a while ago, but it is a definite downgrade for this feature.
