Here he listens without the visuals, so it has to have the musically good elements to rock. That should have been there to begin with, only the listener chose not to give the merit...He had some cloud in his mind (another word - `bias') earlier which probably got removed when he saw the movie...All of us have some kind of bias - sometimes `for' , sometimes `against' and mostly `don't care'...If we have `for', it rocks immediately, even if it is average. If `against', it has to be really great to rock (i.e. the cloud has to be removed by the extraordinary musical or something else).
One can have some kind of objective rating only when the bias factor is `don't care', when a good song is rated good, great song is rated great and bad is dumped for valid reasons...
