ramare's got it right
despite trying to say model a is 'albert' (bullshit, we all know its Axl) MMZXA is probably one of the hardest megaman games period. playing that game on hard requires nothing less than outright abuse of A-trans among other things.
add to that one of the MOST EPIC last boss songs of all time, combined with the backgound, and you get a complete feeling of chaos, and a realization that the End Time is coming for man and reploidkind both, and if you dont stop this in its tracks then its all over, this song and more specifically your remix show perfectly just HOW LONG the damn fights are and the difficulty and frantic pace involved.
