How to transfer downloaded music from iphone 4 to itunes on mac?

Now I don't need anyone telling me that downloading music from the internet is wrong. I know it's wrong but some people just don't have the money to buy a lot of songs, okay? I love music and when I got a new mac, only my purchased music transferred to my itunes. Is there anyway I can get my downloaded songs from my phone to my new itunes?
