jiggyMPD is a Web-based client for the Music Player Daemon and a companion tray icon. It is in relatively early development, but usable now. jiggyMPD extends the MPD data to add features MPD clients typically lack, such as ratings, date added, and last played date. This allows for some unique features. The jiggy data can be queried for smart playlist-type functionality. For example, "added <= 30, rating = 0, playcount <= 2, lastplayed > 1" will tell the client to find all songs added to your collection within 30 days, not yet rated, played 2 or less times, and not played today. It also fetches album art and lyrics.
