Linking iTunes to a network drive.

There are two pieces to your music working on iTunes. One is your media folder, which contains your music files. The other is your library itself, which is typically stored in a location like ~/Music/iTunes Libraries, in a folder containing your library.xml file, as well as folders for your playlists, album art, etc. For your Mac to see the same thing as your PC, you need to copy the iTunes library folder to the Mac.

Otherwise, you can create a new library on the Mac and simply add the music files that reside on the network drive. However, this method will not keep your ratings, play counts, etc.

Even if you copy the existing library, keeping the two libraries in sync is another issue.

 

Yes, but it won't have the same playlists, ratings, etc. as on the PC, unless you copy those over. Also, if you manually added album artwork to your music files, that will show up on the Mac, as well, since manually added artwork is stored in the music file itself. If you let iTunes download your artwork, it doesn't embed the artwork in the files, but stores it in a separate folder in your iTunes library folder, so if you don't copy the existing folder from the PC, iTunes will have to download all that artwork again.
