Uh - no. That was classic (not classical) formless AI noodling on an orchestral bed.
It has multiple structural layers of a sort, which is progress over a few years ago. But they're still a long way short of the huge but intricate structures in real classical music.
I agree, but it's also really weird that such is the case. It's almost like "classical music" is some kind of code word prompting it to maintain a little musical coherence. The others break down rapidly after you listen to them for 5 seconds or so, but the classical-based one holds up a lot better.
From a music producer standpoint if that's the quality for classical music, could definitely create some samples.
