Psychobilly artist Mojo Nixon has been giving away his back catalogue on Amazon this month, and according to a report in the Wall Street Journal has racked up more than one million downloads already.Nixon was apparently hoping to get as many as 10,000 downloads from the scheme, so it sounds like it’s exceeded expectations (just a bit). So how does he make money from it now? Presumably he’s hoping more people will come to see him live, but BigChampagne boss Eric Garland points out another benefit:”The people-who-bought-this-also-bought aspect of Amazon is going to make this really viral within the Amazon marketplace,” he says. So once the music is back on sale again, it’ll show up more often in Amazon’s recommendation system due to all the people who downloaded it. If that’s true, it’s very interesting.
