Samsung Galaxy Player 5.0 Completely Unresponsive


I've had a Samsung Galaxy Player 5.0 (YP-G70) for about a month. I was listening to Spotify today as I often do, and the screen started freezing up. I've dealt with a little lag and freezing before, but this time it turned the screen black, and I have been unable to access anything on it. I tried holding the power button, power+volume up, anything to get it to shut down. It is unresponsive to charging and computer connection. Through it all, the music kept playing (only with earbuds) for 3+ hours. I will let it rest through the night but any advice is appreciated. Thanks!
