Is there a way that I can take a long MP3 file and break it into tracks. I download sermons that are in MP3 format that are at least 1.5 hours long. Unfortunately if I have to get out of my car or leave the room, I can not go back to parts of the sermons that I want to listen to. I also want run the tracks together, so that there is no gap. This will allow me to fast forward quickly to a spot that I want to listen to.
