If you don't use iTunes Match.. get a thumb drive large enough to hold your iTunes library, then export your music from your PC and then import it onto your Mac.
On your PC while in iTunes navigate to iTunes>File>Library>Export Library

Turn on your home sharing options on both the itunes on your PC and the itunes on your Macbook. Then do a "select all" ones you see your old library, hit import at the bottom and itunes will do the transfer for you. It's great. And free (unlike itunes match)
