This movie shines.
You often find yourself clicking around on the desktop aimlessly, but never has anyone reached a "creative plateau" as you have in order to create this musical MASTERPIECE. This is where true creativity comes out - out of the bare basics and with whatever you can use.
I'll give you a 7 for the graphics, because people, imagine animating all of the menus, etc. A lot of motion-tweening there my friend.
The sound is self-explanitory. Watch out Fruity Loops: here comes Sound Recorder!
