I decided to make a new actionscript 3.0 mp3 player (since the old one was AS2.0 and a lot heavier 60kb), I tried to keep it as simple as possible without fancy animation except maybe for the spectrum at the bottom right corner. It’s 20kb and features:

• XML playlist with direct selection
• playlist scrolling position by clicking directly on the scrollbar (instead of using the slider)
• mouse wheel use to scroll playlist (oddly not working here maybe cause of the flash embed)
• play from position when clicking on the time bar
• preloading bar showing on the time bar
• volume adjustement
• mute on/off
• play/pause/previous/next buttons
• small spectrum

Changing the appearance is really simple and takes few minutes to setup (once graphics and main design are done of course) by modifying/editing movieclips on stage. Have a look at the popup mp3player version which keeps the same graphics but with a wider interface.
