I didn't see an answer to this so I'll give it a shot. Qualifier to my answer: I don't have my car yet. No. SiriusXM would have been a good choice IF the car had satellite connectivity for when cell service is spotty/unavailable. Tidal would have been the preferred music source as it is a built-in app to the infotainment system except it doesn't work with HiFi subscription. Amazon Music HD and Apple Music (and Tidal) are the only streaming services listed by Dolby as offering atmos encoded music.
@SaratogaLefty finds that Apple music sounds better even using bluetooth than Tidal. I imagine that Amazon Music would sound similar but be better integrated with Alexa. Based on an assumed better integration with Alexa, I would rank Amazon Music #1 then Apple assuming similar music libraries. I don't have Amazon Music so can't say how extensive their collection is.
If they fix the issues with Tidal, that would move to #1 until Lucid implements Carplay/Auto. If you don't care about atmos encoded music, then any streaming service is fine.
