iTunes Music Store
To access the music store, you must fake the User Agent header to an iTunes User Agent (e.g. "iTunes/9.0 (Windows; Microsoft Windows XP Professional Service Pack 3 (Build 2600)) AppleWebKit/531.17") and load http://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/storeFront .
This is an XML file in what Apple calls a plist format. Parsers can be found on the internet. Usually this returns an action of kind 'Goto' with the url of the store Front page.
