It's not that I lost my "cool" because you don't like Lorde.
It's because of the emotion comment, some people seems to don't understand that music comes in different ways, Lorde's artistical purpose is not to reach a perfect choreo like Beyonce, Jlow etc.
Her goal is to let floating the music through her body.
And since you are British we know the extreme in Joe Cocker or do you want me to tell ,that he wasn't a great artist.
Well, I agree I was wrong when I said that thing about emotions, you're right JC is a good example for it. Hell, many artists do that on concerts. So I guess we're cool.
