I never like the way anything sounds in mono. I like being able to listen separately to each instrument, hear it all spread out into a mental soundscape... mono just sounds like someone is hitting me in the face with music.
Indeed it was a massive step forward when stereo recordings took over from mono. Although when I was a kid our car only had one speaker and the TV too so we wouldn't have heard stereo anyway, not until we got our own hi-fi system.
Cosmic, I love that song but am used to the stereo cut it would probably sound strange to hear it in mono now.
