How to stop podcast playback repeating itself

I really wish this problem could be fixed.  I listen to podcasts on my MP3 player to fall asleep, and while I try to remember to set the sleep timer it is a pain to do and if I wake in the night I am too groggy to remember to do it.  The player just keeps repeating the tracks and runs the battery down and I have weird sleep. 

I moved my files to music as suggested, but then my place isn’t saved in the podcasts when I shut it off during the day or I accidentally knock the player and lose my place (and forwarding is so slow…).  I know you can lock the player but I am subject to constant interruptions as I work and need to be able to turn off the player immediately, not wait as I fumble repeatedly trying to unlock the player.

So just posting in here to add my voice to those asking for a fix for this problem.
