The audio mp3s for the 2008 Desiring God conference are now available. In fact, there are also text and video versions available free too if you prefer those formats.
There are some great talks available from anointed preachers including Mark Driscoll and John Piper.
The 2008 Desiring Conference is based on the power and importance of the words we used, coupled with the wonder of God (as you cold no doubt tell from the image on this post!).
