Just wishful thinking...
Would be great to have Apple Music App in Tesla's.
If Apple makes Apple Music available in Android (outside Apple ecosystem), I do not see any problem having it in Tesla's cars.
Well, since Apple looks to be a direct competitor to Tesla, that's one significant cog. Also Tesla is not using iOS or Android. Not clear how easy it would be or the licensing requirements from Apple. More likely Apple music will be limited to access via Bluetooth due to reasons above.
This should not be difficult at all. Apple already took measures earlier this year (6 months ago? Maybe longer) to enable Apple Music via web connectivity (this was an unannounced move) and just recently announced and made available to all subscriber the ability to enable Apple Music via Amazon Echo/Alexa devices. Apple Music is also available via Android and Sonos. Enabling Apple Music via other services or devices should not be difficult at all.
When we change from Spotify to Apple Music, can we move Spotify playlist to Apple Music? Spotify playlist is protected by DRM protection. We need remove DRM protection, and import converted Spotify playlist to Apple Music.https://www.eelphone.com/solution/spotify-to-apple-music.html
