I am feeling prophetic today.  Let me make a prediction about the direction of the music industry and music downloading.  The price to download a single track will triple from $1 to $3 within two years, but the price to download an entire album will remain at ~$13.  Why?  Too many people are downloading singles rather than entire albums, and there is not enough revenue coming in for the record companies and recording artists.  Having a higher price for singles will not only create more revenue than today, but it will also provide a good incentive to spend a few more dollars and purchase the entire album.  Watch and see!
