Add support for other music services

You need to ask the services to add support to their app. It’s up to them

Very problematic issue. I didn't uninstall the music application as another reader suggested. I turned off "When I add songs to my music on this device, automatically download them here" and "When I add songs to my music on other devices, download them here
too".

Zune and Win8 music apps don't keep subscribed media in the same folder, which is confusing as to where the 'borrowed' music is stored, and has resulted in duplicated files. Another source of duplicated files may imperfectly matched items with the cloud
service.

More settings are needed on the Win8 music app for folder control and such.

If you mean Forza Horizon, then no. The game hasn't been supported for many years now.

If you mean Forza Horizon 4, then probably no. Any music needs to be licensed by the copyright holder, so they can't just add new stuff. You could always just play your own music, either externally or via the Xbox Spotify app (or similar music services.)

This is so dumb. Updates are supposed to add improvements, not remove key features that differentiate the product. Now, it's no different than any other music service. As usual Microsoft takes one step forward and two steps back.

There is a lot of apps the XB1 could benefit from, but from a music perspective, they need to add the ability to use out own music and get music to work while not snapped.

The only cool thing the XB1 does music wise is having the music videos through their service, but subscription is way over priced.
