Fortunately, there's a much more elegant way to liberate your iTunes info: copy/paste. To do this, find the data you want to export--this could be a listing of your complete music library, a playlist of your top-rated TV episodes, or even just the data from single song.
The copy command is only going to pick up the information we see on the screen. To get more or less data on your list, head to the iTunes View menu, and look under view options. If you're just e-mailing a playlist, you probably want to whittle the view down to just title, artist, and album info. But if you're jonesing for more song data, you can also find options for things like release date, or even a record of the last time a song was played.
