Query: Pop Strauss, et al

I was looking for truly Viennese renditions of Strauss waltzes. Though unrelentingly upbeat, this isn't it. There are medleys of Strauss, Offenbach, Rossini, and everyone else imaginable. It's a pop version of what was once pop on its own. I know Strauss isn't serious classical fare, but this trivializes it.
