AmpJuke makes it possible to manage and stream your music online to several clients connected through a LAN or the Internet. In addition to streaming music, it can fetch "metadata" (album covers, images, lyrics, and track "fingerprints") automatically using various Web services such as last.fm and the.echonest. You can scan and import tags from as many tracks as you like, use favorites, and customize personal settings. Its focus is on easy navigation as well as speed.
MPDisco is a Node.js-based music server built to let teams and groups control a single music player together. Accessing an MPDisco server puts each user, after logging in, in a rotating DJ queue. Each user will be given one hour (by default) to control the playlist and music player.
