The new HomePod software update 17.4 lets Siri learn your preferred music service, so you don’t need to manually set it up or always say “on YouTube Music” after every request. It only works with services that support the HomePod, so if you’re a YouTube Music, Deezer, Pandora, TuneIn, or iHeartRadio user, you’re in luck!
It doesn’t work with Spotify, but you can use this workaround to get Siri to play Spotify on the speaker
