I found this tutorial on a website and thought it sounded really cool:
From UKMix, Bhaggers:
Here's this really cool thing you can do to see which words feature the most in your music collection (larger size means more times present):
01 - In your iTunes/iPod library, make sure you only have the TITLE, ARTIST & ALBUM columns up, and then press CTRL + A, then CTRL+C to copy all the words. After you have done that, unhighlight everything.
02 - Go to http://www.wordle.net and click on 'Create'. Press CTRL + V in the box and press go.
03 - Change the preferences to your Wordle using the toolbar
04 - Press PRINT SCREEN on yuor keyboard and paste the picture into Photoshop/Photo Editing Software/ even Microsoft PowerPoint!!!
05 - Crop the photo so only the wordle remains, and then save the picture :
(Photoshop/Photo Editing Software - click on "Save for Web & Devices"; make sure you're saving it as .jpeg/.gif/.png.
PowerPoint - right click on photo and click on "Save Picture", and make sure its being saved as .jpeg/.gif/.png.)
06 - Upload photo to internet using Photobucket / Tinypic.com / ImageShack etc etc. & post link/photo here
Now you try it!
