iTunes Music Store URLs
With iTunes 4.1, Apple has improved URL support for the iTunes Music Store.
As mentioned in the iTunes 4.1: What's New knowledge base article, users may now "Drag a web page from the iTunes Music Store to a document or email".
Beyond this, Apple also allows users to get direct URLs to individual songs and albums by Right Clicking (or Control Clicking) on the iTunes Music Store songs. The "Copy iTunes Music URL" option that appears in the contextual menu now provides users with an easy method of obtaining the URL for individual songs.
Webmasters may also use Apple's new iTunes Link Maker which generates "intelligent" html code for iTunes links.
