This is a very interesting thread. In a past life I worked as a web developer with a couple of websites that used music on their sites but music was not their primary business. The PRO’s were militant on the amount of money they wanted to collect from the websites. They wanted a percentage of the gross revenue from the sites regardless of whether or not it was derived from music. Both of these sites generated mid 6 figure revenues and used a few tracks of music for product demonstrations. They both pulled all of their PRO music and went the non-PRO route. I can’t remember the percentage off the top of my head but I believe it was between 4%-5% of the the GROSS revenue of the site.
