Jon hates half the songs himself, so how could he blame an outsider for not liking them. Didn't Jon say more than once that his music is not even his own wife's cup of tea?

Personally if it was me and I would not have him around if he had said those things. However, it does not seem to bother Jon or he simply does not know he has said them. Either way it is no problem for me if he is around and doesn't like the music that much.
