Element GC-940 mp player -

This product will do that occasionally, and the best way I've found to get it "un-stuck" is to plug it in to the USB port of your computer and that will kick it free of the freeze. If not, then you may have a defective unit (you know how those mass-produced electronics go) and I'd recommend returning it for another. My unit's built in speaker has already fizzled out but luckily, I don't use it at all. I had a second one that I had to return as the USB connection port on the player was not soldered correctly to the board and wouldn't recognize a connection!
