JRiver Media Center is a multimedia application that allows the user to play and organize various types of media on a computer running Windows, macOS, or Linux operating systems. JRiver Media Center is a "jukebox"-style media player, like iTunes, which usually uses most of the screen to display a potentially very large library of files. Regular (usually daily beta) builds are posted on the Media Center Interact forum implementing requested features and fixing reported bugs. The forum has an active member community, with more than 56,000 members as of 2021.
