Might not be fresh, but it's still bangin'
While it's true there isn't much new here, that's precisely why I like this version. Let's face it, part of the reason people listen to remixes of old video game music is for the nostalgia. So of course it would make sense that the remixes should still be somewhat familiar to the listener. But, often artists will stray so far from the original that the familiarity is gone and that's not so fun for the listener.
There's definitely a middle ground to be met between being too much like the original and straying too far. This one is very much like the original, and I'm glad because I couldn't find one familiar enough for me, so thanks. In any case, it's as you said - "It's pretty much the Beethoven's 5th of video game music." - so why stray too far from something that is already great?
