Ok, I am unsure of how this would work - I need help. I would like to keep my iTunes music on an external drive connected to my Mac Mini and be able to access the music from my MacBook. I understand that I can simply share the library and stream it but my big road block is this: what happens if I download music on my MacBook? How do I get that music into the library on the Mini? I'd appreciate any help or even suggestions on making this work with somewhat simplicity. Thanks.
