I have a couple of PCs and a Mac that I have my music libraries on them. Occasionally, I add files, edit artworks and ID3 tags on one of them. I want to keep them synchronized on all of my computer. Any organizational change I make (e.g. update album name, which will reorganize the folder structure) should automatically propagate to others.
What's the best way to do that? Please suggest a free (as in beer) solution (bonus points if it's free as in speech). Better yet, one that doesn't require third party software.
Note that sharing iTunes libraries is not a solution for me as I want to have all my files when I take only one of them and go out.
The issue is resolved with the advent of iTunes 9.0.
