Okay, I got my music loaded and used it in my car with the aux cord, It sounded really good. When I got to work I thought I had it turned off, but apparently not, because when I got in the car to go home and turned on the key, it was still playing and said low battery. Now it's dead. I had it plugged into a wall socket USB charger all day today and I still can't get it to turn on. Hope I haen't killed it!!!! Help!!!!! Thanks, John
