'I wouldn't cross the street to hear Robert Johnson because I don't think he was all that good.(Peace) "Because I don't like the way he sang and played" would be about personal taste, and no one can dictate that. "I don't think he was all that good" makes a claim that goes beyond that.'

Stop being so damned pedantic. Like who you want to like. I'll do the same. Claim that goes beyond? Jaysus. I don't think he's all that good. You may think he's fantastic. That is fine by me. I don't ask that you not like him. I have NO wish to control what you do or don't like, regardless of how you say it.
