Why won't my iPod turn on when I push the power button?

My ipod recently stopped working. At first, it just started shutting itself off and i'd have to power it back up ever now and again. The next day it wouldn't turn on at all until i got it home and plugged it up to the computer.

Now nothings working. Not holding the power button, not holding the power button and the home button, not holding the home button or any other combination of the two. Plugging it up to charge also doesn't help. It shows my power bar and that it's down to it's lowest but it never charges at all, no matter how long i leave it plugged up.

I haven't don't anything that would have damaged it. I've probably only dropped it twice the entire time I've had it, both times on the back and from a short distance to the ground that barely made a tapping noise.

Please help me! I really can't go without music and i don't wanna try anything on my own to fix it without knowing what i'm doing and make it worse. Thanks.
