It's only cool to like rock songs if they sound like 'the streets' (Springsteen), if the band had a serious drug (i.e. heroin) problem or if someone is dead (Parsons, Cobain).
Rock music criticism is an absolute joke. It always has been. It has always been about what is 'fashionable' as opposed to what is actually good. 'Oh dear, I know the Eagles were good. I just don't dare say so or I'll lose my street cred'.
