Software :: CLI Audio Player With Bookmarks?

I've been contemplating making a device for my grandmother and I was hoping some body may be able to steer me in the correct direction for an element that eludes me. My Grandmother is now blind and so can no longer read but instead loves listening to audio books. The family have bought her many audio books but there's a problem. Many of the unabridged books come on several CD's which she tends to mix up when there's nobody around to help. I've tried ripping CD's to mp3 and this has helped a lot however we still have an issue. She can't see which book is which so may be in the mood for an Agatha Christie and end up with the Hobbit.

My thoughts have been make a minimal system combing Festive to read titles of the books in her library to her. The missing element I've been unable to find is an audio player that keeps a record of her position in each book. The idea of course being that she can continue each story from the point she left off, even if the system reboots.
