Speaking of fair compensation for internet material

Folkbum has a YouTube video up that supports the Writer's Guild strike in Hollywood. As much as I think good writing is a commodity, I don't begrudge union member Jay for supporting the union members of the Writer's Guild. I do have one question, though: Are the writer and performer of the song in the YouTube video being fairly compensated for the use of the song at YouTube, Jay's blog, and other places around the internet? I don't know the answer, I'm just askin' here.
