Ollie Wagner & Geoff Pado have just released Misu, an application for your Mac that allows you to "fuse" iPod/iPhone libraries into one. Plug as many iPods as you can into a Mac and "have them intermingle." Misu eliminates the fuss of having to selectively sync and delete and then re-sync again.

Flashback - it's the 1980s, and you've 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; what a pain.

This is where Misu comes in. Ollie Wagner & Geoff Pado's app is for "people who want to discover a whole new world of music." Users simply connect two or more iPods to a Mac, and let Misu "fuse" their music libraries into one, without copying the songs that the receiving iPod already sports - "Misu is smart."

We've had a go at the app ourselves (here, now you try) and the UI (user interface) is indeed slick. You'll find that Misu is not only intuitive, but very smooth as well, using nothing but the simplest icons/symbols and dialog boxes to get you were you want to be as soon as possible. After all, Misu is aimed at simplifying a task that usually takes a lot of time, demanding constant attention from the user.

Misu works with iPod, iPod Touch and iPhone, but you'll need a Mac first of all, no matter what portable device you own. The full version of Misu costs just $19. A trial version of Misu is available right here if you want to give it a try right now.
