I'm not going to say anything negative about your Dad, but from my lifetime experience playing, selling and enjoying music, here's how what I've learned:
Some people experience music as a background in their lives. They like it as a touchstone reference to their youth, but it isn't something they feel particularly connected with.
Other people connect deeply and emotionally to their music. It defines them and shaped large parts of their lives.
I know and love lots of people in the first category. But I truly connect with the people in the second.
