How not to download iTunes Store tracks or previews for Ringtones

We've just received word via Engadget that you may not use iTMS-purchased music or previews as ringtones.

Engadget's awesome Nilay Patel addressed the issue this morning, clarifying that although you can legally install ringtones ripped from your personal CDs, iTMS tracks and previews are off-limits. He writes that the iTMS EULA prohibits the use of downloaded files as ringtones, probably due to its contracts with the music industry. Music ripped from CDs, however, are not derivative works and do not infringe copyrights.
