Replying to IPOD trouble

my ipod, as of late, has begun to play only though the left headphone.  i know it's the ipod, i've tried like twelve pairs of headphones on this bitch.  is there anything i can do to fix it?  or should i just scrap this piece?  also, i'm pretty sure i can do something to my itunes which enables me to take my music from this ipod and load it to my itunes on my computer.  if anyone knows anything about how to either fix my ipod or trick out my itunes please post here.  thanks.
