How to I import music from an iphone to a mac?

So my mom just got the iphone 5 yesterday and so she bought a couple of songs on her iphone. I also like these songs that she bought and I would like them as well. So I signed both the iphone and my macbook pro onto home share using my apple id. But the shared library of my mom's iphone is not showing up on my mac. My itunes is version 11.0.1 and I really need help! Please!
