Absolutely, and I think that is a good thing. I don't care ab initio about receiving money from those mashups because they serve a wonderful purpose without receiving money. However, if somebody who has no relation to creating the mashup—either the fan who spent hours compiling it or those who produced the underlying work being mashed up—is making some money, I'd like to share in it. It only seems fair.
