Sounds this issue similar to you: you are
listening to a long play list
but don't know the title or the artist begin played. Well you could
look at the iPhone/iPod but what to do if the iPod is in your pocket,
it's freezing cold or what ever. In such a situation it would be great
to have iPod telling you what it's playing. And this is what the Talking iPod App is doing for you!
