ZiK is an audio player based on gstreamer. It uses the path of your audio files instead of a music library. Audio files are shown on the left panel as they would be in a browser. The right panel is dedicated to the playlist. Both panels can be shown or hidden. ZiK uses your GTK theme. All formats supported by gstreamer, CDs, and webradios can played.
Gnome Simple Stateful Music Player is a small, simple music player that keeps out of your way whenever possible. It remembers what you were playing when you exited, and continues in the same place the next time you start. It doesn't build a database of your audio tracks: instead it works with your files and directories directly. It remembers tracks you have been playing recently, and allows you to pick them up where you left off.
