MP3/Ogg Vorbis Player Applet (WinAmp clone)
This open source applet can play any MP3 or M3U loaded from your web server. It supports playlist, equalizer, pause, resume, volume and balance features. It's WinAmp 2.0 skins compliant too. You will need JavaPlugin 1.3 or higher to run it. It includes a JavaScript control panel allowing to play/stop/pause, load playlist, ... for HTML developers. It also allows to play file or Icecast/Shoutcast streams (with title streaming support) from any remote server thanks to the self-signed edition.
