Theoretically. Although it would be simple enough to pick out 5 or 6 songs and play them on a loop, which I guess some people wouldn't mind. Personally, I'm not big on game music in VNs, and I tend to mute it and listen to my own playlists on Spotify 90% of the time anyway.
But I'd rather take the time to give each girl her own theme song and actually match scenes and moods to specific songs, which yeah, would take a while. Still, I think music has become increasingly common in VNs now. I used to never get asked about it, but now it seems to come up fairly often.
