Even after background music support is released, Spotify won't be coming to Xbox One
You should probably rule out an official Spotify version on Xbox One, at least for the foreseeable future.
When Microsoft releases the big summer update for Xbox One, the console will be getting a number of much-requested features.
These are, among others, the addition of background music playback, something fans have been asking for since the console's launch in late 2013.
Though Microsoft has yet to detail how the feature will work (whether through the built-in Groove app or the regular player), many were hopeful apps like Spotify will make use of this feature when they release on Xbox One. Unfortunately, at least in the case of Spotify, this won't be the case.
One user asked Spotify support this very question, and the answer was more or less a no. "Right now we're focused on our exclusive partnership with PlayStation, we don't have any info regarding other consoles," read the reply.
If you remember, Spotify and Sony entered into a partnership well over a year ago that saw Sony's Music Unlimited app getting axed, in favour of a new brand: PlayStation Music.
PlayStation Music isn't a new service per se, only a way for PS4 owners to use Spotify and other apps to stream music through it. At the time, Spotify said the console app is exclusive to Sony, and it appears it may still be for a while yet.
