If you bought your music from the Zune store, then unfortunately you won’t be able to play it on your iPod.
Music purchased from the Zune store is in a special format that can only be played by Zune devices.
Apparently, you can get some programs that convert music from Zune format into mp3 files, but I’m not sure how legal that is! It might take a while if you have a big music library, as well.
If the music on your Zune was downloaded in mp3 format, then you shouldn’t have any trouble playing it on your iPod.
However, if you ripped the music from a CD, you’ll have to convert it before it will play on an Apple device - luckily, iTunes can convert it for you, and it takes no time at all!
