Pretty nice, could be improved with colors, though..
With the guitar you speak of, this would be a good idea..
When the player clicks the Fire button (LMB) then it would sound a random note, If they press the jet button (RMB), then it would play a song they selected using /song <name>, it would shoot a shock wave when it played the note ore sound, such as a music shock wave.
Just a suggestion..End
