If it is known that MIDI files of 80's metal bands are the Best Thing Ever,

And it is known that Guns N' Roses is the best 80's metal band ever,

Then one can deduce that a Guns N' Roses MIDI file played back using the entirety of several whole Guns N' Roses songs would be the Best Thing Ever to the infinity plus one.

QED

We believe these findings are reproducible under similar lab conditions.
