It might be the hardest-working app in show business, but iTunes can rock a lot harder when you tune it up with add-ons and AppleScripts--and learn how Smart Playlists bring more of your favorite songs to center stage.

iTunes started out as a smart, simple music player, but over the years, it’s evolved into one of Apple’s most important applications. Although it’s still used for managing and playing your music collection, iTunes now also stores apps, films, TV shows, podcasts, ringtones, and books--maybe “iStuff” would be a better name?--and of course, it’s the sole Apple-approved method for syncing content with iPods, iPhones, iPads, and Apple TVs.

But that doesn’t mean you should take it at face value. Like many of Apple’s applications, iTunes is multilayered. Underneath its simple, straightforward hood, it’s surprisingly feature-rich, offering many powerful configuration options. And it’s time to make that power work for you with our guide to tapping into iTunes’ lesser-known but highly useful features. We also delve into the add-ons that expand the iTunes experience, including the very best third-party applications and highly useful scripts. So fire up iTunes 9.1 or later (it’s currently at 9.2), and get ready to rock!

iTunes 9.2's Greatest Hits

If iTunes were a rock band, it’d only play stadiums. Besides storing and managing your music, the application has to deal with video, books, apps, ringtones, and more. To Apple’s credit, iTunes remains pretty usable, and much of its complexity is kept hidden under the hood. But don’t forget about these useful features.

Library Sources

Uncheck any media types you don't want cluttering up your sidebar.

To change the default media types shown in the Library section of the sidebar, use the checkboxes in iTunes > Preferences > General. If any sources are grayed out in that menu, they’re probably disabled via parental controls. Those settings can be adjusted in the Parental section of the Preferences window.

Import Settings

Set the import format here.

By default, iTunes imports audio using the AAC Encoder set to 256kbps, which is how iTunes Store music is sold. AAC is fine for iPods, but if you use a non-Apple player, you might prefer MP3--head to iTunes > Preferences > General, and click Import Settings. If you’ve got tons of storage, Apple Lossless is the best encoder, and iTunes 9.1 and later can automatically convert songs to space-saving 128kbps AAC when you sync an iDevice (in the device’s settings pane).

Multiple Windows

Open sesame.

Although primarily designed as a single-window app, iTunes lets you open most sidebar components (Music and Connected Devices being exceptions) in their own windows by Control- or right-clicking and selecting “Open in New Window.” If you’ve got a large monitor, it can be handy, for example, to view your music library and the iTunes Store simultaneously.

Sound Enhancement

Pump up the bass, yo!

The often-overlooked Equalizer (Window > Equalizer, or Command-Option-2) has sliders you can fiddle with to adjust the sound, along with presets in the drop-down menu. iTunes can save your custom settings if you choose Make Preset from the drop-down menu.
