Dropped iPod. Now it refuses to copy songs!

I've owned a 2005 iPod Mini (or shuffle?) for awhile now, and it's been pretty sturdy up until now. Fiddling with things in a rush, i dropped it on concrete (for the last time) and when i tried listening to songs on it, it didn't play more than half of them and after struggling on a few it'd just skip to another. These songs were playing prior to me dropping it.

I plugged it into my computer and opened iTunes. I was just going to replace all the songs (thinking i simply corrupted the song-data). Well, most of the ones it was refusing to play won't copy to the ipod saying "Cannot copy specified file because file cannot be found". It's playable on my iTunes but gives me the same message everry time i try to copy them. I've even tried dragging the song directly from the location its at and at that point it simply didn't copy at all with no error message. Alternatively, whenever i plug my ipod in, it works extremely slow, and i cannot eject it. Attemtping to use a proepr ejection does not work at all: ejecting from iTunes causes my iTunes AND iPod to freeze (in which i need to wait for the ipod to die). Attempting to eject from devices just doesn't do anything at all.

I am really hoping i don't have to replace this. I've already restored to defaults but that didn't work. Hopefully there's something else i can do? Any help is appreciated.
