Can I use the same itunes account for an iphone and an ipod?

I have an itunes account for my ipod and i'm getting and iphone soon. I don't want to make another itunes account so can i use the same account without mixing up all the apps and music? Eg. I download an app on my iphone but i don't want that app on my ipod.

Yes. I believe you;re allowed up to five devices on the same account. We have three connected in the family and all have our own apps but only one account.
