"For the last few years, it's been so chic for everybody to be miserable. Like if you're in with the cool crowd, you can't be happy"

In this quote, Lenny Kravitz is talking about a trend he has actually observed in society. He believes that over the last few years, it has become fashionable or "chic" to be unhappy or miserable. He recommends that being unhappy is seen as a method to harmonize the "cool crowd." This implies that there is pressure to comply with a particular image or attitude in order to be accepted by others. Kravitz's use of the word "everyone" suggests that this trend is widespread and not limited to a particular group of people. Overall, he is slamming the concept that being dissatisfied is viewed as desirable or fashionable.
