Transferring songs from iPhone to iTunes

[Macbook Pro.]

I bought a new MacBook today, because my other PC had water spilled on it and would not turn on anymore. This leaves me with a blank iTunes on my new MacBook. However, I have most of the songs from my library on my iPhone. Is there any way to transfer my songs from my iPhone to my new iTunes library? (Most, if not all songs were not bought from iTunes). Thanks in advance for any help!

iTunes match.

I'd prefer a free option, if possible.

Google. Seriously. Google will explain every option you're looking for.
