Highest note achievement
I had a thought based on playing thru one of the At the Movies tracks for guitar for the first time today. Suddenly having to get ready to hit fret 15 (on a classical guitar)! And whoah, I managed to get there in time! I've not played that high on any string before! Then a bit later fret 19?! That seemed crazy. And I missed it, but hey we're all here to learn.
I thought it would have been really neat to have some extra "New record" bit flash up when I finished the song to say "New highest fret hit!" or similar.
