Roon Labs Roon v.1.0 music-playback app

There are dozens of music-playback programs for computers, touchpads, and smartphones, ranging from Amarra, Audirvana, JRiver, Pure Music, and VLC, which manage libraries or work with library software, to programs that are integrated with a specific distribution service: Pandora, Spotify, Tidal, and, of course, iTunes. Still others, such as Sonos, are integrated with a dedicated hardware product.
