I have a sandisk sansa 4gb (no model number apparent). It has worked fine for several months playing (shuffle on) my list of 103 songs. Today, I did something that causes the device to repeat the same song over and over. I can push >>l and it will advance to the next song, but left alone, in simply repeats the same song. I have spent about an hour rereading the menu options and it seems that “play all” or anything like that doesn’t change the problem. Any help is appreciated.
