160gb classic stopped working a couple days ago

My 160gb classic stopped working a couple days ago I was playing a song when it suddenly frooze, the music kept playing but it wouldn't let me change or pause the song. I decided to let the battery drain but now it wont turn on. I left it like that for 2 days then I decided to charge it. The light from the charger indicates that it is charging but the ipod wont turn on. HELP ME GUYS PLSSSSSS I NEED MY MUSIC
