At
http://barcodebattler.co.uk/jukebox I have created a working Flash MP3 Playlist Player.
If anyone is interested in the source code, or in having this on their own website, please let me know.
(update) I have updated this to V1.2 now - it has a track position slider. Youtube has one for video, so it must have been possible for audio, yet so few of the online MP3 players have them.
