This is mostly guesses, and I don't have comments on all of the lyrics either, but here goes:

"One superjudge that brings a change in taste"

-Keeping in mind that 'taste' refers to the sentiments/dispositions that people have towards art etc, this may be referring to a new Artist/Critic who is very influential...

"The new seasons king with a brand new face The old seasons bloom seemed to run its race And we standby for your word"

-This seems to refer to 'the old season's bloom' as what has been considered tasteful by the previous generation, 'seemed to run it's race' would mean that those ideas have been spent, 'And we standby for your word' perhaps meaning that we're all waiting for the new Artist/Critic to give us the new perspective.

"Truth and intent will lose the day Music's revenge to pave the way Play favourites with a view to changing taste"

-'truth' (the old taste) 'and intent' (the interested attitude that the last generation has towards their own generation's art) 'will lose the day, music's revenge to pave the way' perhaps meaning: new music will vindicate the new ideas of tastefulness, and prevail over the old ideas. 'Play favourites with a view to changing taste' perhaps meaning: pick the side that has the winning attitude - i.e.: the dynamic side of the argument (the one with changing taste)

so ultimately my interpretation of the song is that it's something about -changing ideas- especially: ideas about what is tasteful/beautiful/true, through music.
