When it comes to organizing our collections, today's music lovers have it good. We've come a long way from alphabetizing 300 CDs on a bookshelf. Computer-based stereo systems let us store custom playlists for any occasion, create smart playlists that update themselves, and otherwise keep thousands of songs ready to cue up at a moment's notice.

At the same time, all that power can be overwhelming. Let's assume that you've already figured out how to get your personal music library onto your PC or home server. Chances are, everything is not as organized as it could be. Do you know the best ways to find what you're looking for—specifically or generally? Do you tag? Batch tag? Fortunately, organizing your music for fast retrieval is easier than it looks. A little setup time is all you need to make your music experience soar. We'll go through what you need to know to get started with either iTunes or Windows Media Player.

iTunes 7.6

Since its inception, iTunes has hidden the inner workings of its file management, preferring instead to present a single abstract "Library" to the user. This is fine if you like doing things the iTunes way, but it can be annoying if you prefer to organize things according to where all of your files actually reside on your hard drive.

Fortunately, Apple gave in—partway—in Version 7.0, with support for multiple libraries. Hold down the Shift key (Windows) or Option key (OS X) as you start the program, and you'll see a graphic representation of the different libraries you have, along with an option to create a new one.

There are lots of ways you can approach the library structure, such as creating one library for live music and one for recorded albums, or one for each genre. Of course, you're free to go one of those routes. But playlists can split your music along those lines easily enough. Instead, try using multiple libraries to archive music you don't feel like listening to anymore but don't want to get rid of entirely. This way you don't have to stare at it every day in your main iTunes library—think of it as the virtual equivalent of storing CDs in a box in the closet.

Once you've set up a new library, drag all the music you want to archive into it—or just drag everything for a quick and dirty backup. Then, back in your main archive, prune everything you haven't listened to recently: Right-click (or option-click) the bar at the top; check "Play Count" if it's not already showing, and then sort by Play Count. Anything you haven't listened to much—or ever—delete. Don't freak out; it's all backed up in your archive library.

As for the nuts and bolts of organizing your current tracks, each person probably has a special preference with regard to method. Take your pick—star ratings, genre, or the multiple library method, to give three examples. The Genre column is especially powerful in this regard—but only if it's accurate. If your collection is anything like mine, the Genre column is a disaster, with lots of near-duplicates (is it Alternative or Alternative Rock? You're sunk if a song appears on a soundtrack) and missing fields.

So let's redo them all in batches. Highlight a huge pile of songs—of the same genre—right-click (or Command-click), and select Get Info. If you've never done this before, iTunes will ask you if you're sure you want to edit info on multiple albums, so say Yes. Replace the contents of the Genre field with the proper label and click OK—all of the songs will change at once.

Once your tracks are all labeled properly, create some Smart Playlists. Ever create a bunch of static playlists exactly the way you want, only to realize later that they quickly fall out of date? You prepare, for example, the perfect electronic trip-hop playlist, then a few weeks later buy a few more albums in that genre. If you don't add them manually to the trip-hop playlist, they'll never show up. Instead, create a Smart Playlist (File | New Smart Playlist) of that genre and it will always be current, no matter which music you add or delete.

Windows Media Player 11

For organizing your music, importing CDs, and using online music services, Windows Media Player 11 is easily the equal of iTunes 7.6. In some areas it beats Apple's venerable media app. So if you have bad memories about older versions that choked whenever you tried to synchronize your MP3 player, don't fear: WMP is a top-quality app today—in fact, it's our Editors' Choice media player utility.

One of WMP11's strengths is in organizing music by album; it's simply faster at this than iTunes 7 and Cover Flow. And browsing albums by cover is, well, fun. Windows Media Player actually beat iTunes to the punch with this feature. Combine it with Vista's search technology, which is built in to the player, and you can cue up any album just by typing in the first few letters in the Search box and then clicking on the familiar album cover.

The Library view has a number of useful options. Click Genre and you'll notice that all of your music appears grouped in stacks, like stacks of CDs. Stacks are specific to WMP11 and a useful way to organize music by genre or year. Next, right-click Library in the left-hand column and click Show More Views; now you'll see options for Composer, Parental Rating, and the especially useful Folder view, which gives you a birds-eye view of how your music is organized on your hard drive, for enthusiasts who like to keep their folder and file structure in tip-top shape.

About that powerful Search box: To display music from a certain time period (say 1975 to 1979), use two periods and no quotes, like this: 1975..1979. Find all alternative rock music in your collection by searching that phrase within quotes: "Alternative Rock." You can also search for attributes, such as Ratings, by using a colon along with an operator, like this: rating:5 AND genre:jazz. This is much faster than sorting columns and scrolling through the entire library, and it allows for greater precision.

Windows Media Player can help you stay organized, too. Let's say you build a playlist and then find that you skip some of the tunes during playback. In the Playlist pane on WMP's right side, click the triangle next to your playlist's name. In the drop-down menu, there's an option under Skipped Items to Prompt Me to Remove upon Save. Later, when you save the playlist, it will ask you if you want to delete the songs you skipped; this will help you fine-tune your playlists.

Editors' Tips: Music Your Way

Whether you use iTunes or WMP—or just want some new music—here are a few bonus tips for you.

Use Auto Playlists

WMP's Auto Playlist interface packs some power. Click Library | Create Auto Playlist. Then add the appropriate criteria. You can create lists by genre, by three different play count methods, and even by bit rate. Here's another tip: Let's say you're listening to an auto playlist. You can freeze this exact version, before it updates again, as a regular Playlist. To do so, right-click the auto playlist, click Add to Untitled Playlist, and then save it.

Use Playlist Folders

Create Playlist Folders to organize dozens of individual playlists, such as for genres and subgenres, or ratings.

Unorthodox Ratings

Lots of people let the Ratings section go unused, but why not use it as an organizing method? Decide on a love/hate system, or try assigning different stars to different categories, such as 5 for fast, 1 for chill-out or easy listening, 2 for club music, and so on. Then create a Smart Playlist for each of those; as you add and rate new music, the playlists will pick up the new data automatically.

An Endless Supply of New Music on the Go

You probably don't need us to tell you about those newfangled iPod contraptions. But remember that digital music isn't just about static song files—or necessarily about Apple products. Numerous new services such as Internet radio and all-you-can-eat subscriptions ensure that you never get sick of what you're listening to. For a rundown, check out our subscription services reviews.
