Using your Flash 8/CS3/CS4 authoring software, open an existing FLA that includes the MP3 component, or install the MXP and open a new document, then add the MP3 component to the stage and give it the instance name "myMP3" as shown in the example FLA (see download info below).
Add a "TextInput" component (in the Flash component menu under "User Interface") to the stage and give it an instance name of "mediapath" as shown in the example FLA (see download info below).
You will also need to add several lines of action script to the actions panel (scene1: frame 1). The action script can be copied from the example FLA (see download info below).
You should change the color of the background and resize it to fit all of the objects on the stage.
Once you are finished modifying the FLA you should save your project, publish a network ready SWF, and embed the SWF in your webpge. Be sure to add the 'id/name="myFlashMovie"' parameter to both locations in your embed script as shown below:
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0"
width="210" height="50" id="myFlashMovie" >
<param name="FlashVars" value="playlist=tracks.xml" />
type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
You will also need to add the "getFlashMovieObject" and "SendDataToFlashMovie" functions to the header of your web document as shown in the example html file (see download info below).
When loading single MP3 files you should not use the previous and next buttons, playlist component, or images (i.e. to utilize these features, you must load XML files); and you must use the ID3 metadata information in the file to populate the title and duration fields, which means your MP3 tracks must contain ID3 metadata, and you must set the "Title Metadata Source" and "Duration Metadata Source" parameters to "ID3" in the Component Inspector.
