Planet Simpson:

I paid $350 (in US funds) to use a handful of quotes from Radiohead songs in my book. [...] I was not required to fork over a single dime to quote from The Simpsons itself, nor to quote at length from Tony Hendra's excellent book Going Too Far, nor to quote from Foucault or Mark Twain or David Foster Wallace. But to use 87 words from the collected lyrics of Radiohead? Three hundred and fifty simoleons. Roughly $4.02 per word. (Which, incidentally, is more than double the highest amount I've ever been paid per word to write for a magazine or newspaper.)
