LongPlayer extends the functionality of a traditional MP3 player and is meant for people with a large MP3 or Ogg Vorbis collection who want to listen to it all day. It chooses from dynamically generated collections of music to fill the MP3 player s playlist. It does this in a more advanced way than a traditional player, taking into account the rating of the song and the time that has passed since the song was last listened to. The GUI allows you to view, rate, replay, and delete songs previously listened to. It works with XMMS, WinAmp, and iTunes.
