How to put music from iphone onto iTunes?

There's this music on my phone from one iTunes on one profile on the Mac desktop. How can I put that music in a different iTunes of a different profile on the same Mac

I'm currently using SharePod for this method to work. I would recommend using it. ^-^ This program is free and amazing.
