"Prayer Without Words" podcasts - why are they free?

Apparently there is a demand for this type of relaxing, serene piano music. So why would I want to give these tracks away for free when I could just as easily sell them?

I already have much of my music available for sale. But music is not just an occupation for me - it's also a ministry. Sometimes it's good to just do things to benefit others without the need for compensation. This is one of those times.

I hope you are blessed by "Prayer Without Words". Feel free to pass on the blessing to someone you know!
