Perhaps I ought to confess I haven't actually watched this thing through myself, nor do I necessarily agree with everything he says.
I just thought it was worth sharing as a pretty serious attempt at a review from a purely user perspective. We don't see too many of those around

I agree with you.
I found his review to be a mixed bag. His programming of a realistic cover, his ease of use in personally being able to manipulate his way around what he understands about BIAB is great.
His demonstration skills were uninspirational as he clearly has not spread his wings beyond the small arena of use he focuses on with BIAB as a songwriting aid. He gives such a narrow presentation it seemed to me the video was directed toward a particular group, such as a songwriter's club or forum.
He did not have a good understanding (or failed to demonstrate it, if he did) of the Stylepicker. His off the cuff demo's of entering chords and then simply opening the Stylepicker window was horrible. Yet, the result of his serious effort to find and build a great backing track was sensational.
I loved it. It was a great review by what I believe to represent the average user of BIAB. The focus was on the particular area of use the reviewer had for choosing BIAB. He had weeded through the quantity of "everything's" feature of BIAB to mine out the features that addressed his needs for songwriting.
For me, his review gave me a better understanding of a BIAB user's mindset rather than a good technical review of the BIAB software.
Although he lacked skill in completing a competent technical review and missed valuable features such as BIAB having Jbridge to address 64 bit VST's, he demonstrated that with limited technical knowledge of BIAB, one can produce outstanding results.
I enjoyed his review.
