I find statements like this very depressing, and evidence of a fundamental misunderstanding of how words work. 2+2 = 4 is a fact (or, if you want get Fregean, and epistemic about it, an enigma). Your statement simply is an opinion.
I agree that, in context the Smiths were great. That is not inconsistent with the opinion that Morrissey's lyrics sometimes let down Marr's arrangements very badly - "Some Girls Are Bigger Than Others" being the most egregious example. Nonetheless, that is my opinion. It is not a "fact".
