Is it normal to *not* want to share things i enjoy with others?

For example, I met a new person at work and found out that we're both big fans of the same music artist. He wants to go to a concert of his sometime when he's touring in our state. But I actually really don't want to go with him. When I listen to the artist's music, it's got a deep personal connection to me that I don't want to share with anyone else.

For me, going to concerts is easily the quickest route to losing interest in an artist. It's essentially taking the culmination of all these personal experiences I've had while listening to the artist's music and stripping it of anything meaningful by hopping up and down for way too many hours in a mosh pit full of loud, sweaty, high, and generally unlikeable strangers
