Impossible to fully answer that question, from quality pop like Roxy Music to great jazz like John Coltrane, from eclectic electronics like The Boards of Canada to timeless classical music like Claude Debussy (and the list goes on...)
I see. Definitely good stuff there. I worked for a guy (when i was young) who mixed Roxymusic demos for the album. In his studio the music sounded so much better then you can ever imagine. He had the best Equipment available at the time. And the mixing board he used was from Sting. The price on that board was 1000000$ back then.lm not kidding.
Music is just the greatest things we humans have. So much more that can be done, for a very long time.
The best part of music is that there is something for everyone!
