I think these implications would work well. I'm not sure whether an artist name should imply watermark but I included it.
I see one potential problem and that's if an artist included the username of someone else, however I do not think this would be the case and if it were it would be very marginal. Nonetheless if the concern is great enough perhaps instead of artist_name, simply username could be implied.
