The final verdict is in: anyone who doesn't like Neil Young is a bad person.
I'm in the process of accepting Swift (without listening to her music yet--I'm relying on reviews and social media posts until I actually audition her work). Contrary to my initial impression, she doesn't seem to be one of those pop stars who are esteemed because they are pop stars. Apparently there is some there there.
But I've got to disagree with your older male friends: The Turtles were / are a great band. Their day will come.
