What is the exact button combination to use on a 7th gen. nano to get it to say what song is playing?

Thanks for the reply. However I am not trying to use the voice over accessibility feature but rather the text to speech like feature that gives you the song title and artist as listed in the itunes database. I discovered that if I sort of quickly roll my thumb over the top and middle buttons on the side of my ipod I can sometimes get a woman's robotic voice that comes in over the music and gives me that song info without having to take the ipod out of my pocket and look at the screen. This is a great feature when jogging as I can satisfy my curiosity without slowing down too much. I think I need to quickly press the top bottom "volume up" button and then the middle "pause/play" button in sequence but not sure as it does not seem to work every time. So does anyone know the exact button pushing combo that gives this audio song ID info?

That's it thanks. Thought I had tried that option but guess I did not hold down long enough.
