How do I transfer music from my old iPod classic to my new computer with a blank iTunes library?

I have over 700 songs on my iPod classic, a movie, and a few shows.

My old computer, which is totally fried, has my whole library.

My new computer has a blank library.

I want to transfer everything from my iPod classic, or even better, my iTunes library, to my new computers iTunes library.

How do I go about doing this both manually and with some sort of automatic application assistence (i.e., something I can download to do this for me)?

Thank you so much.
