These surveys have the same problems of most surveys, so they are not accurate. There is just so much to unpack:
1.Most people feel they missed "The Golden Age" by being born just a couple years too late. Only if they could have been born a couple years before.....
2.Anything older, has had longer to attract fans. Something good that has been around for 40 some years will have way more fans then something only around for 5.
3.Peer Pressure. Everyone else likes it, so I have to like it to fit in.
4.Idolization. Everyone who is older then you...and cool....likes it. So you must like it to be cool...and better "cool older".
5.Community. When you like what everyone likes, you get accepted into the 'everyone' group'.
6.Timelessness. Your teens are a magical timeless time. You can spend forever....almost...doing whatever you want to do. Even if you do have some work or responsibilities....it is nothing compared to being an adult. In your teens you can do amazing things like buy an album, movie, or video game...and just stay home with it all week end. That endless fun of getting a new video game and playing it for 72 hours until you beat it.
7.The Spot. When asked a question, many people feel put on the spot. They feel they must give the community or popular or cool answer.
8.Free Time. When your a teen, you have near endless free time. You can "follow" whatever with no effort. you are right there and know all about it, and even "feel" you know the people in and around it.
9.Kid's Stuff. A big problem with liking stuff of "today"....is the kids like it. Young people just automatically like things....as it is part of being young. But you don't want to "be like a kid" and say you like something kids like....you like "old stuff".
10. .Closed Mind. So for many people, their teens is a great wild ride where they can explore and experience new things...and are still deciding on "what they like". But for most people....right after being a teen, it's a hard wall. Their mind is closed to new things. They like what they like....the end.
