How to copy music from my iPhone onto iTunes on my Mac?

I have about 500 songs on my iPhone, and I'd like to take them from my phone and put them on my iTunes. Its a new computer, thus a new itunes…

Any programs or suggestions are greatly appreciated!

Step 1 is to log-in to iTunes on your new pc, with your EXISTING Username and Password. Then, authorize your new Mac on iTunes. And sign up for iCloud when prompted.

Once logged in to your existing iTunes Store account, connect your iPhone and it will automatically SYNC, and you will have copies of everything you purchased on your new Mac, and your iPhone.

TIP: Remember that all of your Purchases will be safely backed up, under the Purchases TAB, as long as you don't lose your existing iTunes log-in info.
