Yes, GAry, you are right.
Usually, Will has posted all his songs not only in midi format, but in mp3 format too (at his web page).
It would be great if Will post these songs in mp3 also. It would be great for people wich have not a PSR. They can't listen them in midi format, but they can in mp3 format.
I like specially original songs from Will. He is a great composer, not only arranger.
