Senuti is a simple app that lets you copy songs from an iPod back to your Mac. 

Got multiple Macs? This could be an easy way to put your music onto your extra machine. 

To copy songs back to your computer, all you have to do is select the songs and click the transfer button in the upper left hand corner of the application (above photo).

Features

• Finding Songs — You can search and sort in any combination of ways that you want. That’s not quite enough sometimes, though. Sometimes you might want to know if you’re copying the right song. Know how it goes, but don’t know if that title is quite right? Play it! That’s right, Senuti will play songs directly off of your iPod. It can even double as a jukebox player for your Shuffle or any other iPod.
• Playlists — Senuti not only reads the playlists that you made on your iPod, but it allows you to transfer them back to your computer as well. A simple drag and drop action within the application will not only copy songs to your computer and and add them to iTunes, but it will make a new playlist with the same name and add all of the songs to that list.
• Seamless Integration — Adding songs to your computer, you’re probably going to add them to iTunes right after that, right? What if you didn’t have to, wouldn’t that be great? Well you don’t have to. Senuti will do all of the work for you. What work you want it to do is up to you. You can have songs added to iTunes if you want. You can have all of your music organized into folders by artist and album, too. The option’s yours.
