But in dollar terms, some decisions by copyright holders, rather than optimize the artist’s revenue and distribution, insure the opposite. When I asked to use a single line by songwriter Joe Henry, for example, his record label’s parent company demanded $150 for every 7,500 copies of my book. Assuming I sell enough books to earn back my modest advance, this amounts to roughly 1.5% of my earnings, all for quoting eight words from one of Mr. Henry’s songs.
