                      SoundManager 2 Demo: Play MP3 links "in-place"
                      ----------------------------------------------

                      http://schillmania.com/projects/soundmanager2/

                      A simple demo making MP3s playable "inline"
                      and easily styled/customizable via CSS.

                      Requires SoundManager 2 Javascript API.
