Downhill Battle, the site behind Grey Tuesday, are hosting a rather handy script that allows you to query the iTunes store, and even listen to the previews, from a web browser. The perl script was written by Jason Rohrer (“painter — scholar — poet — lover — scientist — composer – disciplinarian”), as part of his minorGems Sourceforge project.
As Slashdot points out, now that the iTunes protocol has been reverse engineered, it’s now possible to write whatever front end to the shop you want. Well, theoretically. And until you get a cease and desist order.
