I live in Italy and my wife is a classical violinist. Trust me, I'm well versed in classical music, haha. I don't have a choice.
Classical music to me isn't "instrumental music", it's just music. I was referring to instrumental popular music, not necessarily classical scores. The Starbound soundtrack was made by one guy, not an orchestra. No orchestra would play it as it is because it's just too simple. Classical musicians don't like long, simple scores; they're not exactly fans of less is more. The Starbound soundtrack is interesting because it's very atmospheric and moody, and orchestras do not do atmospheric and moody unless they're paid really well for it.
To give you an example, every single classical musician I know thinks this is a shit composition because it's just a very basic progression and harmony. I think it's absolute genius BECAUSE it's just a basic progression and harmony. The strings are extremely simplistic but it creates a feeling that I get that they don't. It's all about perception.
Now, is this less evoking of these feelings than, say, Corelli's interpretation of La Follia? They would say yes, but I say no. I am moved in different ways by both. I don't see how one is better than the other. One is more accomplished and most definitely more involved and complex, but Corelli doesn't make me feel any more warm and fuzzy than Beck's Wave or the Starbound soundtrack just because it's more complex.
Although I tend to dislike Vivaldi's more famous compositions, I prefer his version of La Follia to Corelli's, whose is an adaptation as well. I'm not a big fan of Baroque.
