My 6 year Dell has about 300 MP3's on it. Some D-loaded from Itunes, 2/3's of em from good old Napster back in the day, and some some from other shareware sites. How can I get them on my new iMac thats coming next week? I know there are sorts of software available to use with an ipod but it all seems really complicated. What is the easiest way to do this without getting overly techinical?
