Microsoft just released an update for its music app to address issues that cropped up on the Windows Phone 8.1 preview, such as no Cortana support and buggy interface. Now, the app lets you use voice command to search for playlists you want to list to, pause and play music, etc. Interface transitions look like they are smoother, too. And it woould seem the unexpected black screen issues are gone as well.
