I raised my hand, "My Lord, Beethoven's 9th reminds me of the Sound of Music." He shook his finger at me and the seminarians lost it. Fun days.

...
So, I've actually never heard directly his condemnation of "Sound of Music". If someone has audio/video, I'd love to hear it. Boy this roiled Trads everywhere more than even his saying women shouldn't wear pants or go to university or hold down jobs. In fact, he would have caused less turmoil, controversy, and "scandal" had he come out as a full-blown foaming-at-the-mouth dogmatic SV who held that it's mortal sin to attend
una cuм Masses, became "Feeneyite", and moved in with the Dimond Brothers. I imagine it was because he felt it was too sappy and emotional. I see his perspective, since the treatment of her vocation (or lack thereof) was not handled very well, making it seem like various emotions tugging her in different directions. But he should have appreciated your comment because he acknowledges that Beethoven is a Romantic and admits that he's his "guilty pleasure."
I don't care much for Beethoven (more of a Haydn and Vivaldi fan, with my guilty pleasure being Rachmaninoff's 3rd Piano ... though I don't like anything else he wrote except maybe Piano 2). So, the one exception I make is Beethoven's Violin Concerto. I took my oldest son to see Jewshua Bell performing it, and he was amazing, so I had to give the devil his due. I also like Gil Shaham-stein. I do think Stern and Perlman were massively overrated due to being Jews ... IMO they outright sucked, with next-to-no actual expression in their playing (were in it to earn shekels primarily). But for anyone to say that would be like exposing the proverbial Emperor for having no clothes, so no one would dare ... just like they're afraid to say that Einstein was an idiot and a fraud.
That reminds me also that I was in Chicago at Loyola University (undergraduate before I went to STAS) and got tickets for a buddy and myself to see Stern play with the Chicago Symphony. So I walk in there with this guy and we're both rather "underdressed" it would appear, since everyone else were wearing tuxedos and $1,000-dresses. As we walked past, I could hear a lady with this incredibly snotty tone that movie actors would offer as caricatures, except she was serious: "How did THEEEY get tickets to see Isaac Stern?" I told the guy I was with, since he had heard her also, rather loudly, so that I hope she heard it, "Yeah, wait until I tell her I got them for eight bucks each."

I was on some student promotion from the Chicago Symphony where they reserved a certain number of seats (obviously nosebleeds) for students at very low/affordable prices just to get future generations interested. We were rather broke so we couldn't afford much more, and that's also why we couldn't match their wardrobes. Those where the days were a few of us in the dorm would scrape up pocket change to order a $4 pizza.
