When you buy music using the Music app,
you are buying from the Zune online store.
This store uses points for your purchases.
You buy a certain number of points, and
then when you shop, you redeem those
points to make your purchases. So the first
step in acquiring any music in the Marketplace
is to buy some points.
1 Locate an item in Marketplace, and
2 Click Buy Album.
3 Click Buy Points.
4 Click the option showing the number
of points you want to purchase.
5 Click Next.
6 Click Add A New Credit Card if you
haven’t added one already.
7 Enter the card information.
8 Click Save.
