Welp, this game continues to ruin the erotic scenes by toggling on the most obnoxious music complete with awful vocals.
Unless you are doing a textless montage, using music with vocals just needs to stop. Having to read while horribly grating talking is going on is a bad experience, as it makes concentrating on the words just that much harder. Plus if you do stop and actually listen to it, it's just plain bad discount pop or R&B. Most of the rest of the game the muzak works to effectively set the mood, but the only mood being set by it during the erotic scenes is 'annoyance'.
