The new documentary Downloaded tells the story of Napster, the file-sharing service that ushered in a new era of digital music. Launched in 1999 by a group of friends that met on the Internet, Napster grew to 20 million users -- many of them living on college campuses -- before being shut down by a court order in 2001. Before he traveled to South by Southwest to premiere Downloaded, director Alex Winter (who starred with Keanu Reeves in the Bill & Ted's Excellent Adventure films) joined John Schaefer to talk about Shawn Fanning, Sean Parker and Napster's other co-founders.

Five years ago, guitarist and composer Matt Davis embarked upon a project called “City of Philadelphia, 2008.” Each month that year, he interviewed members of various communities around Philadelphia – and then wrote music inspired by those conversations for his ensemble, Aerial Photograph. Now, Matt Davis has brought his ensemble and a new iteration of his project here, to New York. The group joins us in our studio to play a selection from “City of New York, 2013,” as well as an older piece called "Nondum." 

The Harley Davidson Motor Company recently made news when it banned all music from its factory floors. No more headphones, no more radios, no more piped in music. Now, of course, this ruffled some feathers… some rather large, burly ones. But let’s face it – music can be pretty distracting.

However, a new online music streaming website called Focus@Will is betting on music as a way to keep listeners focused – particularly when they're trying to read, or study, or work. Founder Will Henshall joins us to explain the science behind the service.
