Björk has hit another important milestone in digital music distribution. Rather than releasing her new album as a typical digital download, she is introducing her Biophilia project as both an album and a “mother app” that will house interactive song apps. The Guardian reports:

One song, “Virus,” features an app that appears to ask the user to stop an attack by a virus on a biological cell. However, if the user succeeds, the song stops playing. The user learns that they must allow the virus to accomplish its purpose in order to complete the song. App creator Scott Snibbe describes it as “a kind of a love story between a virus and a cell. And of course the virus loves the cell so much that it destroys it.”
