Views
The three buttons between the status windows and the search box in iTunes let you switch between the list view (default), the grouped-with-artwork view, and the cover browser.

Using iTunes’ cover browser is like sifting through a bin full of albums.

Browser
Press Command-B to send iTunes into Browser mode. This is a great way to peruse your library by genre and artist.

Columns
Add or remove the columns you want by pressing Command-J. A list of column options will appear; just check or uncheck the ones you want or don’t want to appear in your list.

Say it With a Script

You can use AppleScript, Apple’s scripting tool, to automate and control iTunes. Our favorite repository, Doug’s AppleScripts (free) for iTunes, has more than 400 AppleScripts—there’s a script that removes missing tracks, a script that can pull songs from your iPod and add them to iTunes, scripts to remove duplicate tracks, script to add song lyrics to a song, and a lot more.

Visualize a Better Visualizer

The Visualizer is eye candy, but why not make it candy that you like? Instead of sitting there and staring at the Visualizer, use these key commands to change its behavior.

Plug-ins

Add variety to your Visualizer by installing one of these iTunes plug-ins.
