We've previously looked at how bad Xbox Music is on Windows Phone 8.1 (in the Preview for Developers, anyway), but the experience has never been flawless on Windows Phone. Microsoft evidently knows this as the company is looking to roll out an update next week (April 22nd), which will kick off bi-weekly releases for the Windows Phone 8.1 Preview client. This is superb news for Xbox Music Pass holders who wish to have a decent experience on the phone.

Joe Belfiore even tweeted that a new app will be released for those who are using the Windows Phone 8.1 Preview, but it's good to see an actual change log be present over on Microsoft Answers. If you're interested to know what's on the way, here's what Microsoft is looking to include in the April 22nd update: Numerous stability fixes, including many of the reported black screens

Cortana integration is complete and now supports playing playlists by name

UI polish to improve animations and transitions between UI views

Improved messaging for encountered errors, such as unplayable content in collections

Background initial sync of local and cloud content
