Heading to the Store and version 2.6.155.0 for Xbox Music and 2.6.154.0 for Xbox Video are now live for downloading and updating.

True to their word, Microsoft has pushed out two new updates for their Xbox Music and Xbox Video apps for Windows Phone 8.1 . Microsoft is on a tight schedule, delivering updates to those apps every two weeks in an effort to bring them to par.

Currently, both changelogs filed "bug fixes and improvements" as being in this update. However, the teams behind the app has updated their User Voice pages with specifics, which are listed below:

Xbox Music 2.6.155.0

It's faster to load your collection, particularly the collection lists and artist details

Scrolling in your collection album and artist lists is smoother

While your phone is charging, the app will opportunistically sync with your cloud collection

Better messaging as your collection builds and syncs with the cloud

We also fixed a number of bugs! A few notable issues we addressed:

Album art not appearing (or incorrectly using the Xbox Music catalog version) when present in local MP3s

Scrolling through a playlist being jerky and seeming to scroll infinitely

Shuffling your collection having too few songs, and including duplicates

'New music' items showing either twice or not at all

Xbox Video 2.6.154.0

Quicker loading for personal video, movie and TV show collections

Expired rental downloads are now automatically cleaned up to free up disk space

Additional bug fixes

Head to the Store to download both updates and let us know what you think in comments! (Users may want to re-pin the Xbox Music app to their Start screen after the update)
