Can you use iTunes music store cards to purchase applications, TV shows etc. from the iTunes store?

I have amazon credit that I want to use to purchase an iTunes gift card to use to purchase applications and TV shows from the iTunes store. However, the ones that they sell on amazon say "iTunes Music Store Card". Are these only good for purchasing music or can they also be used to purchase other things from the iTunes store?|||The iTunes Music Store Cards can also be used for the apps store which is part of the iTunes Store so you can buy games, movies and TV shows.
