Theory: Web Based MPD Client [Music Player]

Theory is a mostly Ajax web based MPD client which features a self-contained web server, Amazon album art fetching and, like it's author says, "not ugly".

Other Theory features include:

• drag/drop playlist reordering
• fullscreen "party" mode
• tag-based but includes a simple filesystem browser
• lyrics fetching from lyricwiki.org
• semi-accurate linking to the artist's wikipedia page
• custom randomizer
• optional (very simple) authentication
