In fact, taking this further, I find this similar to people who have a Netflix account asking for suggestions on what they should watch. Back in the 80s, did we ever walk into a video library and ask the person browsing nearby, "which film should I watch?".
NO! Because you'd pick up the empty Betamax/VHS case, read the synopsis (or look at the cover), and decide for yourself if you want to watch it or not. Netflix includes a film synopsis, so why don't people read them and decide if the film is worth watching? If you wanted someone's opinion, you'd watch Barry Norman, not some random Joe Public.
Granted, choosing a film is slightly different to choosing hi-fi as video libraries didn't offer the possibility of sampling a few minutes of the film, but there are many dealers round the country who will allow you to do just that - let you listen to what you want. You're in control, you can choose what to listen to, and reject anything the "salesman" suggests. But for some reason, people feel more comfortable asking strangers than listening with their own ears.
