Also, I would like for disc tags to be properly recognized in Zune. Before you tell me they are, go to Collection>Music>Songs. In this view (which is just a long list of your music), sorting by album ignores the disc tag so you end up with tracks going 1,1,2,2,3,3 like WMP again.
I think that's by design. I don't think they intended for people to use the 'song' view as the main view. In the other views the software takes account of the disc number.
Still, it would be nice if they fixed it. It shouldn't require more than a couple of lines of code to implement,
If it's by design, then it's the stupidest ****ing design ever.
My WP7 takes the disc number into account. Zune in the Artists, Albums and Genre views all take this into account. So why not the Song view?
I'd say more an oversight than a deliberate design. Though I doubt many people use the songs view in the way you want to (not that that is any reason for Microsoft to not spend 30 minutes adding in an extra few lines of code to add this feature).
I'm not at my Zune PC at the moment, but can you check to see if it is possible to add the 'disc' column to the song view? I think you right-click at the header of the list and 'choose columns' or something. If you can add the disc column you should be able to sort by disc.
