it’s interesting, almost strange, to see that you view 'Trance' as streaming music, because I think of it strictly as club music....
Interesting that you say that because I can guarantee you I never went to a club not even once in my entire life. I just don't like the idea of it.
I did go to some open air festivals though, but I very rarely if ever heard Trance in any form there.
I did hear some Euro and Dream Trance classics from the 90's in some Water-themed places and activities like hydro-gymnastics and Aquaparks though. I heard Children, 9PM and Better Off Alone in places like those.
I also remember hearing some other Trance classics on the radio even before I became a Trance fan in late 2008. I remember Kaycee - Escape being played on the radio or some events of the time back when I was a little kid.
But, for the most part, Trance Music has always been a personal at home, walking and sometimes running activity. Actually I could not care less about clubbing or festivals, for the most part. In fact, I've always liked Trance because it has always worked really well outside the club/festival scene.
And I can guarantee you as well that Trance has always been way more than club music. I remember tracks like Drifting Away or Take Me Away being played as radio songs, in fact, back in the 90's and for a great part of the 2000's there were many compilation series like Dream Dance and Future Trance which would include mostly radio edit version of Trance tracks although not exclusively Trance tracks. Streaming is just a natural extension of that. And considering how for the most part the so called "original version" a.k.a. the current edited version tends to have far more streams than the extended mixes show Trance like many other genres are streaming music. Thinking of Trance Music and Electronic Dance Music as a whole as "strictly club music" is actually incredibly reductive in many ways.
But, as for the topic itself, for the most part this isn't wrong. Unfortunately attention spans have dropped significantly in the last few decades. This is mostly the algorithm and social media's fault. Unfortunately this has permeated into music too. Nowadays people want easy quick dopamine fixes. Sometimes they don't even make the track run until the end, and this is something I've noticed happening since as early as 2016. I remember seeing people skipping a track after the main chorus happened which would probably be after 1:15 or something like that, which was extremely annoying to me because I was enjoying a certain track and then all of a sudden they skip to the next one. So, as you can see, this trend is actually older than one would expect.
And even I myself have become somewhat a victim of this as well. Long gone were the times when I would regularly listen to 10min long Trance and Progressive tracks on a regular basis. Even I myself admit to be somewhat a victim of this as well.
Plus, we have to have something in mind: Some extended mixes are not even available on streaming services themselves, heck, not even on YouTube sometimes! And even the extended mixes themselves for the most part have become pretty much pointless for the most part nowadays. The only thing they do is add some build-up before the important/relevant part of the track and then a quick outro to it. For the most part the extended mixes only serve as DJ-friendly tools and pretty much nothing else these days.
In my case, I'm not a huge victim of the algorithm myself because I like to search for music on my own, although the algorithm does give me some recommendations. But, for the most part, I just see what my favourite artists have released on Spotify and I do look for some algorithm recommendation on YT while trying to look for some new or undiscovered music myself.
