So I just got a macbook pro and I want to manage my songs on it instead of the home computer, which is a pc. I do home sharing with my family, and they want to keep the songs on the pc as well. If they buy a song, I want to be able to have it and vice versa. How do I do this? I am using icloud, but I don't know how that works.

If you have iTunes on the PC, then you can use Home Sharing to access the music on the PC.
