Somehow my iPod Nano 6G (the small square clip-on Nano) has entered a mode where it shuffle plays everything, even though I am not starting play with the Shuffle option at the top of albums, songs, or playlists. I think that this is new behavior; I'm certain that I've been able to start an album or playlist in the middle or at the first item in the past, and have it just play everything sequentially. I've tried powering it off and restarting it (not just putting it to sleep, but seeing the little rotating status bars on the dimmed screen). The sleep/wake button is set to Play/Pause, and Shake to shuffle (all options in Settings > Music are off, in fact). Help!
