That said, I think that a possible explanation for the decline in club popularity is that a lot of people don't actually like it unless they're on drugs. Not just the music, but the whole club scene. It might be an acquired taste, entirely possible, but it's not a taste I ever felt the need to acquire.
Not quite apples to apples, but similar, about a year ago I realized that I actually don't like living in NYC. Moreover, I realized that I never really liked it, and I had been trying to convince myself that I did for the last decade. I don't like how expensive it is, I don't like going to bars, I don't like hipster art stuff, I do like the train, but not having a car is still inconvenient, etc. There's a million things that I know a lot of people in NYC really like (and more power to them if they do), but I do think that if people were more honest with themselves there would be a lot fewer people living in this city.
