Muxic is a minimal user interface to XMMS2. It is inspired by Winamp Classic's windowshade. It is only meant for controlling and monitoring playback, not for managing a media library or even a playlist. To actually play music, it relies on the XMMS2 (the X-platform Music Multiplexing System 2) daemon, and another XMMS2 client must be used to put some music in your playlist. Muxic's keybindings are based on a subset of Winamp Classic's keyboard shortcuts. Muxic announces track changes using Growl.
BackPlay a program that plays music files from a folder in the background. At login, it scans a directory called "BackPlay" under the user's Music directory, and begins playing any music files it finds there in random order. BackPlay is independent from iTunes. It can be paused from an icon in the status area.
