With a Zune Music Pass subscription, you can download, stream, and listen to as many songs from Zune Marketplace as you want, as often as you want.
You can download and sync Zune Music Pass items to a combination of four different computers, Zune players, and Windows Phones. For example, you can download music to your home computer, work computer, laptop, and a Windows Phone. Or if you have multiple devices, you can download music to one computer and then sync that music to one Windows Phone and two Zune players.
Once you've downloaded or synced music from Zune Music Pass to a computer or device, that computer or device is associated with your Zune Music Pass. If you want to change the computers or devices that are associated with your Zune Music Pass (maybe you replaced your home computer), you can swap out a computer or device every 30 days.
Note
To use your Zune Music Pass on a Windows Phone, make sure you sign up for a Zune Music Pass using the primary Windows Live ID that is associated with your Windows Phone. If you have multiple Windows Live IDs, see What to do if you're using multiple Windows Live IDs and the Windows Live ID Selection Wizard to help you choose which Live ID to use for your Zune Music Pass.
You can only use your Zune Music Pass on phones that use your Windows Live ID. Zune Music Pass is designed for a single user. If other members of your household have Windows Phones, they will have their own Windows Live IDs associated with their phones and therefore will need their own Zune Music Pass.
