I'm sure he got to hear a variety of music growing up with you, Mess. I also think that kids that learn to play an instrument and certainly that play in a band grow to appreciate other players. I recall my frustrations playing in bands when I was young feeling like we could not get to the "sound" I wanted to get to. So, I always appreciated other players. 

My goddaughter heard Yo-Yo Ma when she was very young and fell in love with the cello. Her dad loved cello and so was always playing his stuff. When she was just walking I played guitar for her and she heard it and immediately walked up to me and stood there with her hand on my leg balancing herself while she listened. When she was about 5 or 6 she was at my house and I put The Beatles movie Yellow Submarine on for her. We watched it together and she was completely mesmerized by it. She asked me "Are we the only ones in the world that know about this movie?" and I laughed and said "No, lots of people know this movie." and she said "They should be playing it all the time then."

Now she is 17 and got her first guitar last summer. It is an Ibanez acoustic that looks just like the one I was playing for her the first time I played for her. Her father said to me, "I took her to the music store and told her to try out guitars until she found one that she liked. She picked that one." He sent me a photo from his phone with her sitting in the music store playing it. He said to her in the store "That's just like the guitar uncle Reggie has." she said "I know."
