bit annoying...
The idea is alright, and it is amusing, but there is room for improvement.
You could ad some more power ups, don't let the ball appear randomly in the middle of the screen (this is most annying), and try to see if you can get a less repetative music.
coming back to the music, if found a small bug. If you press the music-on button, while the music is on, two music track are started. just a minor issue, but worth looking at it.
