I dont believe the statement that buy age 30 your set in your musical choice
I do. I'll go so far as to say by age 22 or so. I think you and I are outliers. I don't know of or have heard of anyone middle age or older in my local sphere, at work, at the gym, or really anywhere except the Web who listens to new artists.
There was a thread here recently called "Share albums where EVERY SINGLE song is good". I commented that almost every album mentioned was 45-50 years old. Nostalgia is a powerful thing.
Occasionally you'll see audiophiles scoot into some other genre on a temporary adventure, but it doesn't suddenly displace their favorites. You rarely see experimentation with non-audiophiles.
You also see "getting stuck" as I call it, in the guitar community. You'll see guitarists consistently stuck playing songs from a 5-7 year period that aligns with their late teens and early twenties.
This isn't just about music. Look at technology. How many people over 40 outside the computer profession (and even inside) understand things like cryptocurrency or the internal workings of blockchain? Blockchain is the future. Eventually all immutable documents will be stored on a blockchain. All your contracts, your deed, your loan agreements, etc. will be on a blockchain. Yet no one over 30 outside work knows what the heck I'm talking about. At most they think blockchain is Bitcoin.
One of my theories for "getting stuck" in the music of your youth is personality type. Without getting too deep into clinical terms or study citations, it's well known that some personality types are more curious than others. For instance, Sigmas have a very strong curiosity trait. Elon Musk is probably the most famous Sigma. No surprise there. Sigmas will do stuff like start new technology companies, dream up high-speed tunnels, commercial space travel and even have the cojones (or naivete, or both) to think he could start a successful car company where all others had failed. But Sigmas only make up 6% of the population.
Is breaking out of "getting stuck" in the music of your youth only limited to Sigmas? Could Sigmas be the outlier in this regard? Or might it have something to do with people who work in professions that require constant change develop an immunity to fear of change? Or something else? I don't know. But I do know that I've tested as a Sigma and I'm one of those people who never got stuck.
