Help - Mac newbie and iTunes

Hi everybody. I'm quite new to the Mac world, completely satisfied with my new iMac 20", but now I have a question...
I created an administrator account and my personal account. Is there any way to share the music that I downloaded from the Apple Store when I was logged under as administrator with iTunes in my personal account? I tried few times yesterday, but completely without results...
Anybody can help? Thanks a lot in advance!

Thanks a lot. I will check this evening and see if it works...
