I added songs to it and everything. The instructions say when I plug in the headphones wait 2 seconds and it will turn on. The music should play automatically. But for me it doesn't. It says to charge at least 1 hour before first time using it. I guess maybe I can't charge it right. I connect the USB to the USB port and that's how it should charge. They said the buttons should light up but it doesn't. Can someone help me???
