How do you wipe all the songs out of an IPod Nano?

There are two ways to do this!

First, you can set the iPod back to factory settings, thus erasing all synced content and ressetting any changes you have made to the iPod itself. Hook up the little bugger and open iTunes if it doesn't do so automatically, then from the lefthand menue click on the tab that has the name of your iPod such as 'iPod Nano or Ryan's iPod or HOTMAKEOUTIPOD'; whatever it's name happens to be. This will open up the ipod menue and you should see a wee button that says 'Restore' on it. By clicking and confirming this, the iPod's drive is wiped of personal data and it goes back to the way it was when it was first pulled out of the box!

or, you can manually erase all the songs by going to the music tab under the name of your iPod in the iTunes menue, selecting the first song, then pressing SHIFT once you've reached the bottom. That will select all the songs in your library and then by left clicking and selecting delete, backspacing, returning, etc depending on whether you have a Mac or PC, all the songs will be removed from the library and, upon resycing, on the iPod, too.

These instructions work for all iPods, by the way. (: I hope all goes well in your quest to swipe those songs!
