You don't have to get a new one, there is nothing wrong with your iPod.
I don't use iPod, but my daughter has for years, she says that you can get a free download program which will move your items from your iPod to your Computer. The program is called "senuti" which is iTunes spelled backwards!
Anyway, she says that it works like iTunes, but in Reverse, so you can move files from the iPod to your computer. Once you do that, and your files are safely on your computer, when you go to Sync your iPod, it will zero it out, but you will have the files on the computer and then can restore them to your iPod.
Here is an address for the free trial:
