Hi. When I was in college I used to listen to everyone's itunes playlist's which was a great feature. Now at home, I wanted to listen to a family members and it says that they need to be authorized to listen to there music and vice versa. 1. If they give me the authorization does that take away one of the 5 they get? 2. Does that mean I have two authorizations on the same itunes? 3. If I am living with someone and we both have bought itunes music before how do we share? 4. How would you set this up? We are thinking about getting the new apple base station because we both need to use an external hard drive. If I put my music and the external, and she does to, do you recommend combining them into one huge collection? If so how do you do it and would I be able to keep all my ratings for every song I have?
