regarding Danny's VERY insightful observation about growing the audience while letting the musicians come because they see money changing hands....

I'm about to retire. Growing this site will become my full-time job after retirement.

When my son and I started researching the feasibility of sites like this, we googled and found a few (but not many, considering the overwhelming potential) similar sites.

We noticed right away that about half of them were dead. No activity for months. Yet others were dynamic, active and growing.

The difference is that the dynamic sites all had somebody working the paradigm every single day. I will be doing that... mostly because it is in MY best interest to draw new money to the site.

And the musicians who are using the service for free and earning money in the process will benefit as a result.
