If you're weary of first visiting the home page of the iTunes Music Store and then traveling to the areas of The Store that really interest you, this tip will help.
Launch iTunes and drag to the Desktop links to the areas of The Store you often visit. For example, if you want to view the page that displays The Store's Top 100 Songs, drag the Today's Top Songs entry to the Desktop. When you do this, the entry turns into a Web Internet Location file.
To put this file to good use, launch iTunes and then double-click the file. Your browser will launch and then iTunes will come to the fore and load the page associated with the link.

Updated to add: If you'd like to create an Internet Location file for a genre page, go to The Store, select a genre from the Genre pop-up menu, and, once you arrive at the genre page of your choosing, drag the genre button (the one next to the home button at the top of the iTunes window) to the Desktop.
