I prefer to listen to my textbooks rather than read them. Problem is, most chapters are 1 hour to 3 hours. I've tried the onboard mp3 player for Motorola Defy's and Win Amp, but with each of them, if it accidentally gets shut off and you don't know where you were in the audio, you're just out of luck. Is there an mp3 app out there that will load right where you left off if it gets shut down? Thanks!
