How to take music from iphone 3 and put it on laptop?

I had some music on my old laptop which i no longer have, and from there I had a ton of songs that I moved to itunes and put on my iphone. Well, I need to get them off my iphone and into my new itunes. They were not purchased through itunes, so they won't come up.

Please Help! I know my iphone is old, but it's all i have:/

There's no way to get back my other itunes because my laptop broke so now i just need to move them from my phone to my new itunes. How do i take them off?

I downloaded this software.http://download.cnet.com/SharePod/3000-2141_4-10794489.html I've used this personally and it's helped me so much. This is completely virus free and reliable since your downloading from CNET. When finished downloading, you will be asked that you have your iPod/iPhone plugged in. When the software opens up you will the all your songs. Select all of it and click "Copy to Computer" The default folder where it will store all your music in is the Music folder. To find the music folder, click on the windows start menu and to the right should be something listed like "Music" click it and all the music imported should be there. Now you can just drag the folders into iTunes where iTunes will sort eveything out, and where all your songs will be. Hope you've found this useful as it was for me!
