With no documented source work or creator attached to the title, million high qual part 3 circulates online purely as a labelled segment of a larger audio sequence. The part 3 wording suggests viewers were looking for a specific section in higher quality, rather than the full clip from the start. That split format is common on soundboards, where short excerpts are saved separately for fast reuse. It remains used because a numbered, high quality excerpt is easy to find, drop into an edit, and recognise when building a longer sequence.
