Who cares if she doesn't write her music? He comes off as pretentious and while he is right, he doesn't express himself clearly. People don't have to write lyrics but they have to be great/excellent at something like singing, dancing, performing or even be passionate about their own music. She isn't good at anything really and on that point, yes she is not an artist but that has nothing to do with how much she writes.
I agree on the Coldplay's part though. They suck so much.
