This is a pretty unique new software tool that lets you copy music directly from one iPod to another. I haven't seen anything like it yet... the interface is slick and easy.

Flashback it's the 1980s, and you just made a mix tape. You dubbed some tunes and gave them to a friend. You'd think it would be that easy to share tunes with your friends today just plug two iPods into your Mac and have them intermingle. But it's not. iPods are normally locked down, and you would have to selectively sync and delete and re-sync to get where you want to be; what a pain.
Enter Misu. Misu is for people who want to discover a whole new world of music. Just connect two or more iPods to your Mac, and watch as Misu fuses their music libraries into one. And Misu is smart; only the songs that the receiving iPod doesn't have already will be copied. The slick interface lets you do all of this with ease and pleasure. Within a try or two, you'll know you need to give Misu a home in your apps folder (or on your iPod Misu is mobile!). So give Misu a try get a taste of what the Mac is missing.
