Hi,

No, unfortunately Apple Music isn’t currently available on Xbox consoles and most likely won’t be for a while.
Xbox One and Series X|S console apps - some apps may not be available in certain countries/regions. It’s up to the app creator/developer to decide where their services are available.
If you’d like to listen to music while playing a game, Deezer, Spotify, Pandora and SoundCloud all allow you to do this.
You can also listen to the radio in the background. TuneIn or iHeart Radio is probably the best option for this with music stations.
Apple TV, however, is compatible with Xbox. I believe this is the only Apple service supported on Xbox consoles at he moment.
Don’t listen to any rumours from untrusted sources, any confirmed news and future updates would be posted on the official Xbox Twitter page @Xbox and
https://news.xbox.com
If you’d like to suggest a feature or app, you can voice your opinion and share ideas and any feedback on the Xbox Idea Hub on Reddit.
Just FYI: You’ll need to be connected to Xbox Live (not offline) to use any of the apps mentioned above.
Hope this helps :)
