I have a new Windows 7 computer and after installing iTunes I can upload new music but I cannot download it to my iPod.

Hey AppleMacParker,

Thanks for the question. The following article may assist you in setting up syncing with your iPod:

iTunes 11 for Windows: Set up syncing for iPod, iPhone, or iPad

Select items to sync automatically

1. Connect your iPod, iPhone, or iPad to your computer and select your device.

2. Select the type of media you want to sync.

The types of media you can sync depends on your device. For more information, see Sync and organize iOS apps and Add photos to iPod, iPhone, or iPad.

3. Select the Sync checkbox, and select the items you want to sync automatically each time you connect your device.

Click a button to select the kind of content you want to sync, then select the sync checkbox and select the items you want to sync automatically

The bar at the bottom of the window shows how much space will remain on your device after you sync.

Thanks,

Matt M.
