iTunes Sharing Through Airport Extreme

[Joe Ferguson]

I am having difficulty sharing my iTunes using IP. I am able to load and
listen to other's iTunes playlists but can not get past what is needed to
share my music playlists.
I'm using iTunes 4
I have firewall on but have created port 3689
I am suspecting that there is something amiss with my Airport settings.
I am able to find my IP by using IP Addresser X 2.5
With so many others using Airport for internet connection I'm hoping there
is a workaround.
