does anyone know why music skips when transfer songs from ipod to computer and how to fix?

I have transferred my music by using the Home Sharing option and all of my songs are now skipping? I am trying to transfer from old iPod to computer so I can move to new iPhone but don't want to transfer a ton of skipping / crappy songs....

Anyone have this happen to them and know why this occurs and if it can be fixed?

Thanks,
