Why is my iPod nano reading everything out loud and functioning abnormally? I just reset my iPod nano 7th gen via iTunes to remove some broken tracks and then resynced it, and when I unplugged it after disconnecting it, everything was quite broken.

First of all (with a headset plugged in) the iPod is reading everything out loud....screen dim, music, double tap to open, etc. But then, in conjunction with this, I can't control the screen like normal...you have to double-tap to open anything and I can't swipe side to side to get to settings so I can't try to change whatever mode this is. When you slide a finger over the icons, a little selection square moves over them with you.

What's going on?
It's in VoiceOver mode (an accessibility feature). I don't have an iPod nano, but on iOS, under General, there's an Accessibility menu where you can turn it off.
