PLEASE NOTE: MiniLyrix is not fetching lyrics from the internet!!!
MiniLyrix is a iTunes companion app that shows the lyrics of your currently playing iTunes song. The lyrics are taken from the songs id3 information.
It displays the lyrics in a nice semitransparent overlay window. You can switch between an always visible floating window and a temporary overlay from the systems status bar. The font size can be changed with '+'/'-' within the resizable floating window. Additionally MiniLyrix provides basic iTunes controls.
