Those who played the PC version first probably get nostalgia from the PC version's music. When I first played S3&K on Sonic Mega Collection, I was really shocked by how drastically different the music was for three of the zones and originally preferred the PC version's music because it was what I was used to. Nowadays, I'd much rather listen to the Genesis music but I still like the PC version of Carnival Night Zone, Ice Cap Zone, and Launch Base Zone. Heck, I find the PC version's music for ICZ and LBZ to be pretty underrated. Granted, the Genesis version of ICZ is vastly better but I always liked how the intro to the PC version of LBZ sounds similiar to music from the PC version of ICZ and then goes in a very different direction which seems fitting because the level starts with snow.
