It may not be the majority of downloads but it will be a considerable portion of the downloads from the few sites mentioned on this thread.

I didn't mention 'roadtesting'. I said I download or go to the library for recording I wouldn't otherwise buy.

As for libraries and loans royalties, that's an illusion. I never received any anyway, or from broacasting. The crux there is you need to subscribe to your national music rights organisation to receive anything and in most cases of the artists on the download sites in question the membership fees for these organisations will way outstrip the royalties due.
