On my Mac upstairs I have a play list of songs that are only on that computer. My house is NOT networked at this time. I have a wireless router. However, the strangest thing happened. I was on my iTunes on the PC downstairs and noticed my play list from the Mac computer was also on the pc...I never imported any songs onto the pc. I cant even use those songs on my Ipod cause it doesnt drag but I can listen to them on the PC and the Mac...anyone have an explanation? And perhaps how can i get the music from the pc on my ipod..(ipod is pc formated)....Thanks for everyone's help.
