Necessary Discrepancy is a cool song. I think it is interesting.
Melody
Due to what is said in Evolution, some parts don't sound the best. Also a bit slow at times.
Evolution
I don't remember where I saw this mentioned, but the song gets more orderly as time goes on, as if Ramlethal is slowly understanding the world around her (and emotions).
Emotion
Gains more emotion as the song goes and Ramlethal understands more. The chorus and ending mainly carry it
Bangerness
A bit slow, and I am not the biggest fan of the part before the ending. The chorus and ending are quite good though.
Characterization
I think this works well for what Ramlethal has become post-Xrd (and even just post-Sign).
Lyrics
Like Symphony, Necessary Discrepancy randomly lists words, this time being emotions. It also has some parts in Latin(?), which add to the idea that Ramlethal doesn't fully understand the world and those words yet.
