I have a signifigantly large library of music currently on my PC. I purchased an iMac and need to migrate the music oveer to the iMac, then I need to sync my iPhone that has never been synced with ITunes anywhere. (Currently no music on the iPhone) How do I move the library the easiest (I have an external drive) and then selectivly decide what songs or play lists gets synced to the iPhone? Lastly, I did load some songs on the iMac, shold I remove before migrating to avoid doubles or will iTunes recognize this and not recopy the songs. Thanks for the help and advice in advance.
