Misu: Add music from one iPod to another
Misu is the perfect program for those who are tired of using iTunes to exchange music between two iPods. This nifty little program allows two iPods to connect to each other and seamlessly merges their music collections. Any song that you don't have from the other iPod will be added to yours.
The process is simple and easy. Just connect both iPods via the USB entries on your Mac, launch Misu, press 'Transfer', and let it take care of the rest. While exchanging a large number of tracks may take some time, the application is fairly stable and requires little knowledge to run.
Although it would have been nice to browse through the other iPod's library and select only the songs you wish to transfer, Misu still offers a convenient way to exchange music in one go.
Overall, Misu is the perfect program for effortlessly adding music from one iPod to another.
