There are a lot of way to answer this question, in the following lines I am going to point out my favorite 3.

Over the years people have came up with a lot of ingenious methods in transferring music from one ipod to another. They have invented softwares that trick iTunes and have even created gadgets to speed up the process and make it even more simple. At the moment there is only 1 method that really lets you transfer music from ipod to ipod directly, it is explained below as the third method.

The first method that allows you to transfer music is a really basic one. Let's say you have some songs on your ipod that your friend really likes. If you have those songs in your computer you can add them into an archive and send them to your friend via email or instant messenger. He can then add them to his itunes library and you are all set.

The second method implies softwares. There are more softwares that let you do something like this, the best are: ipod2ipod and flool. These are a bit complicated but if you manage to figure them out they work pretty good. They allow you to transfer music from one ipod into the computer and then back to another ipod. This is a method worth checking out.

The third and last method, my personal favorite, is the only one that allows you to transfer music from ipod to ipod directly. This implies a little gadget called miShare. This is extremely simple to use. You just add the songs/images/videos even playlists to your To-Go playlist on your ipod, connect both ipods to the mishare and hit the only button it has.

Now if you are ever asking yourself "How Do I Transfer Music From iPod to iPod?" just take the time and try one of this methods out, if you think the first 2 are complicated, then just use miShare, it does all the work for you.
