Kinda. Lots of vague generalizations. “Let’s assume the seller takes 50%” (which sellers take that?)
“Let’s assume $2” (most were a bit less).
Why only list sales by single on the EP? There’s no mention of the EP sold as a whole.
And then “this project took a year of my life and COST me money”. This is his job ... he obviously must have made something from it or have some savings that he’s not mentioning - it’s not like you can work to make a loss consistently.
