Return to "Now Playing" on Zune
If you start listening to music, then navigate away, there is no menu option to get back to the “Now Playing” screen (with the album art). I found this shortcut: press the pause/play button twice. It interrupts the music for a moment, but there does not seem to be any other way to do it.

But on my Zune 4GB, (ver 2.3), If I navigate away from Now playing, and leave it as it is ,after few seconds it’ll automatically return to Now playing screen.
Excellent point – I should be more patient! I also have found that, depending on the screen you are in, pressing pause/play twice will cause a DIFFERENT track to play.
