Forgive me if this is the wrong place...have searched all over for a good audiobook player. Every one I downloaded from the marketplace only played their own downloaded books. I have 4 on my phone now. Finally found one that works with MY audiobooks, free app. Mortplayer. It works. Haven't used it much, but so far so good. Sorry if this is inappropriate, but I would love to help someone else searching for the same thing. It took me days of searching (when I had a few spare minutes I could have spent listening to an audiobook) to find this. If you have a better app or suggestion, I'd love to hear it.
