The features of this mp3 player are: Auto Start on/off; Shuffle Play Auto Start on/off; Scrolling player buttons; Sound spectrum with changeable colours; Song thumbnail; Shuffle play; And other standard controls and display. You can add this player to your projects because it is within a single movieclip on the stage. The player is not designed to be resized. This player is also designed to be embeded directly into a .html page. You can change the graphics by editing the relevant movieclips in the library.
