Early 00's I used to listen to my brothers playlist on Windows Media Player. One of the songs was a gloomy/trance(?) remix of classical music. He had named it (something) Beethoven mix.
On multiple occasions I tried searching for it. Both the mix and the original song to make the search easier. But since I'm not at home with classical music I couldn't figure out either of them. Not sure if it even was one of Beethovens pieces.
