So this is kind of cool: a $10 program called iTunes Catalogue lets you create an HTML version of your iTunes music, which you can upload as an HTML file for your friends to share. And if you click on an album or artist it will take you to the iTunes music store.
For what it’s worth, here’s a partial catalogue of my music. The version I used is a “trial version” so it doesn’t create a complete catalogue, but at least you can see how it works. Unfortunately, the program only works with Mac computers.
