Microsoft is preparing a version of Xbox Music that will offer access to its subscription, storage, and track-purchasing service beyond its current Windows 8 and game console iterations.
"A Web version for Xbox Music will launch next week," a Microsoft spokeswoman said. "We will have more details to share then."
The news of the Web version was first reported by The Verge.
Microsoft baked Xbox Music into Windows 8, when the operating system debuted in October. The company used the leverage of its dominant operating system to help spark the service's business as it competes with iTunes, Spotify, Pandora, and others.
The Web version of Xbox Music is likely to offer music streaming though a browser. Microsoft had said that it will create versions of the service for rival platforms, such as Apple's iOS and Google's Android mobile operating systems, to be available sometime this year. It's unclear, though, if that will be part of next week's announcement.
