This is simply not true. Define "high quality" with regard to music. Give me an example of both high quality and low quality music. It would be exactly the same as defining "good" and "bad" music. Who gets to decide what is "high quality" and what is "low quality".
(Answer: Each individual listener = subjective)
Take your pick. Three amateur versions of Europe's "The Final Countdown" picked from YT.
Would you not agree that you can use very objective ways of measurement for quality to pick one song over the other two ?
Things like how much was each participant on pitch and in time during the duration of the song.
