Strictly speaking, no you can't do it. There are ways to do it with varying bits of software (I use Tunebite but you have to pay a tenner for the privilege and you have to know what you're doing tbh, because the instructions are a bit crap). There are some mners, I think who use some free software but, I can't remember what it's called.
For all things Apple related, you can't beat this site its excellent. You'll find the answers to pretty much any question you can think of, and their forums are pretty good. I speak as one with a problematical ipod, who has had oodles of help over there.
