Why is my ipod shouting everything at me?

I must have triggered some bizarre mode and I don't know what it is or how to turn it off.

I can't get it to happen predictably-- whenever I try to make it talk, it won't. But whenever I try to just put on a song and listen, it starts saying the name of the song and artist, then reading off the names of random playlists even though I'm not using a playlist; I always just pick out of Artists. And it does it repeatedly, it won't %^@#ing stop. It's infuriating. I'm trying to listen to a song and it just keeps telling me the name of the song.

Is it broken??

It's the newest nano.
