My 4th gen Ipod nano keeps getting stuck on the apple logo.

My 4th gen Ipod Nano keeps getting stuck on the Apple logo screen, this happens everytime I plug it in to charge. I plug it in, an apple logo comes up, and it stays like that the entire time its plugged in. To get it to unfreeze, i have to press random buttons and unplug and re plug in earbuds. After 20-25min of doing this it unfreezes and I come to find it has gotten little to no charge after being plugged in for hours at a time. Any one else have this problem, and if so what do you do?
