I’ve noticed that “weirdness” as well - not finding songs and artists, but I thought playlists were ok. For example, “Hey Siri, play a playlist.” <<Which playlist did you want me to play?>> “Baked Alaska” <<OK, now playing Baked Alaska>> Then my holiday music playlist plays normally. I can even ask Siri to shuffle the songs. Yesterday, I tried some experiments, which were sort of inconclusive. It seems the more “unique” the name of a song or artist, the better the chance of Siri “finding” it. For example, “Hey Siri, play ‘Love Games’” <<OK, now playing “Never Going Back Again”, by Fleetwood Mac.>> Me: ??? Then I asked, “Hey Siri, play ‘Take me to the Mardi Gras’ “ and the song plays normally. Can’t add the artist name to any play request though or Siri will be sure to indicate that you don’t have that song/artist. Maybe I’ll make my money back my monetizing a video of some creative way of destroying this formerly excellent, but now useless and frustrating device (x2).
