If you refer to the instructions that came with your iPod, they will recommend installing iTunes on your computer. No worries, the program is free. On top of that, it is the only method of downloading software updates and is the easiest way to get media on your iPod. Unfortunately, programs like Windows Media Player will not sync music to your iPod.

You’ll notice that Quicktime will install alongside of iTunes. This is mandatory in order to download music videos, or other forms of video from the iTunes store. It also doesn’t take up much hard drive space.
Upon installation, iTunes will also offer any other programs you may use, such as their web browser, Safari. You do not need to install it, but if you wish to learn more, you can read my review of it here at Bright Hub.
