ugh...
ok where to start...
first of all... do you know what key your even playing in? some of the notes were clearly not supposed to be there.
the backing beat neeeeever changed, and as far as I can tell... there's not really a intro. The other instrustraments just came in out of cue.
music needs to flow, or otherwise it can be a real pain in the arse to listen too, you can't just throw in piano assortments and beats, and expect it to just "work".
I can't tell if this is a joke, if it is, it's a horrible one.
