Why would I have comments on what you sing ?

 Do I need a reason to comment on your singing ? That whole things were not started so I could compare to others singing. I try to say how to sing. 

They American have the whole industry where they come from. 

No, I don’t have any opinion how I think you sing. I don’t listen to music, in case you didn’t know that. There are certain things I hate doing ....many.
