how to move your iTunes library from PC to Mac...

So Many ways...

If your old machine is a PC here is a link to several solutions... http://support.apple.com/kb/HT4527?viewlocale=en_US&locale=en_US it lists 5 different ways to move your music. Just click on the method in Blue you want to use. Home sharing is another good method. Or setting up an external hard drive to transfer the music. Plus you can set it up to be your 'Time Machine' (apple speak for backup drive). But I go off subject.

Also I recommend buying iTunes Match. The best deal for backing up all of your music. It costs $25/year but beats burning 500 million dvd backups. Plus it backs up music you didn't even buy on iTunes. Then you can easily access the music on your apple devices. This also might be another way of transferring the music. http://www.apple.com/icloud/features/

And just in case I haven't confused you enough you can also set up your ipod to be an external drive and transfer the music that way... http://support.apple.com/kb/HT1329?viewlocale=en_US&locale=en_US

Now if you are transferring from one mac to another it is really easy. Use the 'Migration Assistant'. Here's an article from Mac life about how to do it. http://www.maclife.com/article/howtos/how_move_your_itunes_library_new_mac
