How to Post an MP3 in My Facebook Wall

Upload the MP3 file you would like to post to your website using your standard upload process.
Navigate to Facebook at facebook.com, and sign into your account.
Click the status update text box, and enter a link to the MP3 file you are hosting at the end of the status update. If you include commentary about the file, make certain that it comes before the link to the MP3 file otherwise the embedded MP3 player may not be displayed.
Click 'Share.' The MP3 file will be playable from your Facebook wall and your friend's Facebook news feeds.
