Help using home sharing to download music from one mac to another mac, same owner.

I have tried all morning but I am unable to download songs my home connect. I have logged into both and I can play the music on the new computer. However, I can't download any of the songs. What am I doing wrong? I just want certain songs on this new computer instead of my whole library.

I also can't find the "Show music not on this computer" option either.

Thank you
