Hi everyone,
Using a simple keyword "lyrics" (with no arguments), my workflow searches Rap Genius for the current playing song in iTunes.
I am open to feedback, feel free to share bugs or potential improvements.
Update:
Using fn and control as modifiers, you can now look up the current playing song on Spotify and Rdio, respectively.
