If anything I toned down my reaction to this to stay within GN's rules. This new version of Engage the Enemy has had the emotional tonality completely gutted by the tacky, ridiculously out of place use of operatic vocals.
There are no nostalgia goggles involved, music is and always has been one of the most important things in the world to me, my father is a professional jazz musician and I've been brought up surrounded by music. I am usually the first person to champion live orchestrations, but and in my opinion, the orchestra sounds too small and there are things in this new arrangement that are vastly inferior to the original. In fact I just gave my old man a listen to the original Engage the Enemy and then Trailer and he, an incredibly knowledgeable 81 year old musician with no nostalgic ties to the game or the score, also agrees that the new vocals sound jarringly out of place and only detract from the composition.
Xenoblade is my second favourite RPG of all time, you could go as far as calling me a fanboy as well considering I own the full four disc soundtrack. I could just as easily counter argue that you're letting your self-confessed fanboyism blinker you to criticism. There's a reason why the FF10 remastered ports all included the original soundtrack as an option and it's not just 'muh nostalgia'. Arrangements can go wrong, they can be inconsistent, they can be good but still inferior or even miss the mark entirely, and yes, they will hit everyone's ears differently. In the case of Xenoblade, this is possibly the biggest disappointment I have felt in a long, long time.
