Did you grow up in the 80's or 90's with Chciago House music?

Do you know were the Warehouse is/was? Have you shopped in Gramaphone Records? Ever been to the Rear? When Mayor Daley acknowledged Chicago's role as the birthplace of house by proclaiming August 10, 2005 to be House Unity Day, did you consider it a religious holiday? If you can answer yes to these questions, you may be able to help me. Do you know where one can download, legally and safely, House Music from the early years? I am talking about Too Cool Chris, DJ Frankie Knuckles, Thunderpuss, etc. I have an iPod so songs have to be iPod compatable. Thanks for your help.
