No, your response was not merely highlighting a difference of opinion.You started by saying that you "struggle to see how anyone who was to take the time to examine their output could fail to admire them" and finished with the opinion that I do not "have much aptitude in assessing the quality of music" and that my comment "holds no credibility".
My point is - just accept that people think differently to you. You don't need to struggle to understand why I don't appreciate something, or pass judgement that my lack of appreciation for something is because I can't "assess the quality of music" (whatever the fuck that means).
Let it go. It's just music, bud.
