While the Xbox One's dashboard isn't finalized yet, he added, the Xbox Music app will be part of one of the main areas.
Initially the paid-only service will have limited use. Music won't, for instance, be able to play in the background while a person is playing a game. Instead, if someone wants to listen to songs from Xbox Music they will have to run it in snap mode, which takes up some of the side of the screen, and manually turn down a game's audio in the game's options.
The app will also not include any SmartGlass support for controlling music at launch, Johnson said.
"The focus for launch will be getting the player out," he said, "but then SmartGlass will come along."
Johnson said that the company has a lot of ideas about how they can expand the service on the Xbox One and that work they're already working on them internally.
