From the developer:
DesktopLyrics is an application that displays the lyrics of the song currently playing in "iTunes" right on your desktop. The lyrics for the song have to be set in iTunes, DesktopLyrics does nothing to fetch lyrics if they aren't available in iTunes.
DesktopLyrics does not only display the lyrics but can also display the information about the current song (e.g. title) in a customizable manner.
