No, I certainly feel emotions that are true and so do you. We all do. For example, You are clearly bothered by me asking you to explain what in particular you felt was so lacking in true emotion. It's clear you can't articulate this and perhaps you even know that you were being judgemental and just threw out a criticism that might not be true without thinking about it too much. The interesting thing, to me, is that it is your "true emotion" that prevents you from saying something to the affect of: "on further reflection there are true emotions going on here."

Of course these young people are experiencing true emotions. They are clearly feeling this experience. They're doing something daring; risky even. They're having fun. They're making music and having experiences. The music itself is very emotional. The singer is literally screaming into the microphone with anguished energy. Whatever you feel about this music or this act of taking over a metro train, the one thing that is clear is that these people and this music are full of emotions.
