Tell me what you think about my music

Artists are always looking for “what people think” about their music. This really translates to “tell me something positive so I don’t freak out”. If this is the intended purpose, why ask in the first place? I had a band send in a demo and ask me to tell them what I thought of it. After listening to it 2 or 3 times, I crafted a long email pointing out what I thought were the strengths and points to work on, plus asked for some clarification on certain things, as I was interested but not sold. I never heard back from them.
