Thoughts on music - is this really true?

This isn't a rant but the premise is something that made me think.
It doesn't annoy me in the slightest but made me consider how I now perceive music the way I do. And why that might be so.
This post on The Line of Best Fit got me started because it doesn't fit my experience at all. I will soon turn turn fifty and yet now I listen to not only more music but a wider variety of music, both new and old, than I ever did  - as a teenager or any time in between - and I estimate by an order of magnitude, so statistically significant. In part that is because I can but that does not mean that that I would do so if I did not wish to do so. Indeed I am rather proactive about finding new music rather than simply waiting for it to be served up to me by the industry and established media. Again this is something I rarely if ever attempted back when I was younger. Is this largely peer group pressure and the fact that as we get older, and in general terms more self-assured, it influences us less?

Let's look more closely at what the primary research implies. I will start with this graph:

On the face of it the indication is that I am just an exception to the rule. Another is that I  and many others are listening to "cool" (contemporary) music but also a whole lot more other "uncool" music as well?  This chart does not tell us that, and conveniently stops at age 48. I assume that means that I am regarded as a "dead" listener now.
Strange then that I am writing this. The rest of the survey is interesting not least because it seems to indicate that females' taste in music ages much less quickly than that of males. Interesting though it is I suggest that it might be influenced by factors that are not the headlines - the data is based on US Spotify streaming. What if females are more inclined to use Spotify more often than males, and possibly at different ages, as just one example?
There could well be very legitimate reasons for that to be true; this study tells us absolutely nothing about them.
The certainty is that a lot of money depends on divining the real trends in music consumption and the demographics of it. Importantly, and this must be true given long-standing trends, that it will vary dramatically from country to country, which is something else that the above survey, quite transparently, makes no attempt to address.
