Entirely subjective. Listen. If you wrote the Interpol song and in your original version or score the G# did resolve to A, and then Interpol plays it and doesn't resolve the G#, then you might be able to make a case for calling a stylistic choice a "mistake."
A misstep, perhaps, but certainly not a mistake. A poor judgement call, because you wouldn't have done it the same way, but certainly not a mistake.
I stand by this unless the bass player from Interpol hops up on this board and cops to not wearing headphones when they were recording this song, and then, I don't know, being ill when they mixed the song, and he didn't hear the non-resolution until it hit the radio and everyone/everything was unalterable and committed.
I guess I didn't know that there was a Complete And Perfect Universal Rulebook when it comes to crafting music.
Certainly, choices offend our own personal musical lexicon. But it remains a stylistic choice.
I can - or perhaps even better - my mom can call Lou Reed's Metal Machine Music amazing, or a giant waste of time, or noise or beauty, but to call it a mistake is to completely do disservice to all of the decisionmaking and personal effort that went into the craft of sound into music.
A mistake is an action.
A decision is a direction.
The problem with the Interpol song is precisely that he used the G# as the destination note when it was supposed to be a passing tone and in fact it would have worked beautifully and completely along the aesthetic lines they're so entrenched in if it had in fact passed up to the A.
Perhaps that's exactly why they didn't resolve it.

I said that all good music contains dissonance
Are you saying only dissonant music is good music?
You're going to have to elaborate on this (or provide examples).
