headcanon that Encom programs and human Users have almost entirely non-overlapping preferences in music
most program music sounds like incomprehensible machine noise to Users, and most User music sounds like pretty much the equivalent to a program
it’s possible for either side to acquire the taste for the other, but it’s rare
further headcanon: the whole artistic range of the Wendy Carlos soundtrack represents the entirety of the overlap in which music will generally appeal to both programs and humans. (Even the most User-friendly program music will still strike humans as having that sort of… beautifully eerie, otherworldly quality to it.)

My very first Tron fanfic was very much about music, including the idea that Wendy Carlos’ music would hold a special significance to Programs if they heard it.
