Recommendation Please.... How to get Bookmarks in an AudioPlayer?

[Raging Idiot]

Received such good/quick feedback on my last question that I figured I'd throw this one out there too.

I have over 200 audiobooks, +music, +video...and I want to be able to stop out of a book and be able to play something else and then be able to come back and play where I left off.

Each audiobook is broken down to multiple mp3's, one mp3 per each chapter, just like songs in an album.

If I could at least have it remember which mp3 was played last in each playlist then that would be great, although perhaps not ideal. Some of these books have just one long continuous mp3, so it would be beneficial to know just exactly where I left off in that specific file.
