Since getting an iPod all of my music is on the computer. Playing music from the computer is imo a lot more convenient than playing CDs from a stereo. Now I'm looking for a program that will allow me to play music in several different rooms in the house. I'd like to have seperate volume adjustments for each room so one room can play at level 3 while another plays at level 5, for example. If I could play differnt play lists in different rooms simultaneously that would be great. Any recommendations for software than can manage this task?
