Ha good laugh.
I can see the beginning where the kid seems very timid while playing, but sticks in there for a little longer just to hit a few more wrong notes. That's of course when he can't handle it anymore and just slams the keyboard.
I think this would go pretty good in this scenario of a flash. "Kid is playing piano, makes a few mistakes, but keeps on playing. Then makes a few more mistakes, gets pissed off, and slams the keys on the keyboard. Heavy metal music starts to play and he starts screaming along with the music."
Nothing too complicated in the script, but this song could be useful for something like that. The song itself that you made was so simple, but yet funny to a point. Not too bad at all for the purpose that you made it. Hopefully someone uses it some day.
