Do You Think There's as Many Obsessive Fans for American Artists?

I feel like NorCal and SoCal people all congregated in LA to watch the show. I was going to buy one but I couldn't find a good place to buy it online before the concert because all the reviews are like oh mine came fake or whatever whatever so I was goingto buy it at the venue. But the lines were so long. Do you think there's as many like obsessive fans for American artists? I want not obsessive we can use a different vocabulary to this guy fan. Right right right. Sorry.
