Tagging files in your iTunes library helps you find the music you want to listen to and lets you create smart playlists. And album art gives you a visual reminder of what you’re listening to.

What exactly are tags?

Tags include such things as the name of a song or film, a track number or a genre. A number of other tags tell iTunes to do certain things, such as skip files when you’re playing music in shuffle mode. The Summary pane of a track’s Info window shows many of its tags.

When you buy music from the iTunes Store, it comes tagged with all the relevant information. And when you rip your own CDs, iTunes looks up the tag information online and adds it to your tracks. You’re free to alter the tags.

There used to be a ‘Has Artwork’ option in iTunes for smart playlists. How do I get that now?

Create a smart playlist (File > New Smart Playlist) with Album Artwork in the first pop-up menu and Is True in the second to see which tracks have artwork. To see which tracks haven’t got artwork, choose Is False.

How do I delete album art from a group of songs?

Select all the relevant files and press Cmd-I. You’ll see an Artwork pane in the lower right corner of the resulting Get Info window. Tick the box next to this well, and then click OK. This deletes all the art – even if there are multiple covers – for the selected tracks.

I like to add personnel and set lists to concert films, but the comments field is too small. Is there a way to add more information to video files?

As odd as it sounds, your best bet is to use the Get Info window’s Lyrics tab. It holds approximately 24,800 characters, which should be more than enough room for your needs. You’re free to add pretty much all the information you want in that tag.

You can see many of the tags in the Summary pane of the Info window for any track: the name of the track, the artist, the album and much more

Is there a way to save my place when I’m listening to really long radio shows?

Select the file from within iTunes, choose File > Get Info or press Cmd-I, and click on the Options tab. There you’ll find a Remember Playback Position option. Tick the box next to the option and click OK.

Not only does iTunes remember where you left off, but if you sync that track to an iPod or iPhone, you can pick up from that point on your portable device as well. Each time you sync, your current place gets synced as well.

Many of my songs segue into each other. How can I make iTunes play the segued songs together, even when shuffling?

The best way is to join the tracks when you rip a CD. To combine segued tracks, select the files you want to join and choose Join CD Tracks from iTunes’ Advanced menu. iTunes places a bracket next to the tracks that it will join when you click Import CD. I perform this manoeuvre often, especially for live The Cure staples.

If you’ve already ripped the tracks, Mac owners can use the free Join Together to join them (dougscripts.com/itunes). Be sure to read the instructions, as some of its functions are limited under OS X 10.7 Lion.
