Itunes/Ipod Help needed!

[xKingpinx]

So I had to reformat my computer due to certain reasons...and I reinstalled iTunes and now when I connect my ipod it asks if I want to Erase and Sync. Basically wipe my ipod and replace it with stuff from the library...which is currently like 5 songs I purchased a while back. This has happened before and I have fixed it but I forgot what was needed to be done so that I can sync my ipod without wiping it clean. Any help would be greatly appreciated

I have looked on google....but to no avail. Nothing helped me that I found..

There's a folder somewhere in the ipod where all the music is kept. All the sound files are in random folders and have weird names.

Just copy the folder to your desktop, erase + sync, add the folder to itunes, sync again.
