Lethem, DJ Spooky and others on copyfighting and creativity on public radio

A recent episode of Public Radio International's To the Best of Our Knowledge dealt with remix, reuse, and plagiarism, talking to some of my favorite people on the subject:
Author Jonathan Lethem talks to Jim Fleming about his "Harper's" Magazine essay, "The Ecstasy of Influence: A Plagiarism." As the subtitle indicates, Jonathan Lethem appropriated the words of many authors to cover the subject of plagiarism, although he provides full attribution of his sources at the end of the essay. Also, Paul D. Miller (aka DJ Spooky, That Subliminal Kid) talks to Anne Strainchamps about his book, "Rhythm Science," and how the art of music sampling relates to plagiarism. We also hear a DJ Spooky/TTBOOK interview mashup.
