Well, im assuming that since you say it works great, hat it came with songs on it, or you got songs on it from someone else. Or maybe you just turned it on and assume it works great

What i assume your looking for, is a way to get music onto your ipod without using the software that came with your ipod? Well if thats the case then I can help you out.

That is a program that was developed for windows, but the guy in my next link says that he had problems with that program on ME.

That site walks you through transferring songs to your ipod with Me. If your ipod is already formatted to be used with windows, then you can skip the first few steps. This method requires winamp aswell.
