:"best known for" is in all cases, without exception, a subjective statement which cannot possibly be verified.  In the example you give, you'd want to put something objective like "...their greatest commercial success came with 'TITLE', which reached blah blah blah."  But no-one's tried to enforce any standards for years and years and years, and have instead rewarded idiots who have never created any content with power.  So there are very few editors who can even tell the difference between subjective and objective these days.  Seems like you might be one of them.201.215.187.159
