I would remove MX completely.Ok i have removed the chords that where out of place and only kept the relevant and needed ones on the [HD] diff.
For edits to HD: 00:22:845 - 00:37:845 the double notes seemed over used. They didn't match the lyrics. I would use single notes to match the beat and Double notes when the lyrics match the beat.
Same problem again around 01:06:691 - 01:16:500 before streams start.
The streams themselves feel like just notes thrown in to play tbh. they match the beat but that's all.
The parts with the LNs make the most sense and are most fun to play
thanks for the help~
