Just to share, my wife and I, after thirty-one years of marriage, enjoy many of the same things. We have a common love for a few bands and, sharing a taste for many of the same kinds of music makes it easy for us to listen to the same things. It's not just about music. It's everything. I never had to change myself a bit for my wife to fall in love with me. Nor did she have to change for me.
The point of my thread to begin with had nothing to do with married couples or even people in love, per se. It had to do with changing who you are and what you like because you think it will make them like you. I've known people who have lived that way and made the same mistake time and time again. Particularly a couple of friends of mine who today are a couple of spineless drones without voice or spirit.
