MiniLyrix

MiniLyrix is a iTunes companion app that shows the lyrics of your currently playing iTunes song.
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.
Please note that MiniLyrix can only show lyrics that are available within the files id3 information.
