I've been using this since version 2 with very few problems. Setting it up the first time was a bit confusing, but only because I don't know anything about networks, etc. However, the author has been very quick to help me with every step, and the forum members are very generous and fast with their help.

After I got it set up and working (which took only a few hours), I've never had any problems with it.

If you want to share all or just a few of your iTunes libraries or tracks, this is a great app at a very reasonable price with excellent support.
