I use streaming services a lot.
In guitar lessons I'm constantly referencing music on Spotify for students. Inevitably I have to look up a song, and most times the following thing happens:
Spotify chooses to pull up the LIVE version of a song. Or an alternate version.
If I tell a student "listen to this song this week" again - most of the time it's not the definitive version, but a live version, a remix, or an alternate take. Something about their algorithm (and it seems YouTube music is similar, I don't know about Apple Music) makes it pick the least common choice.
As I'm writing this I'm listening to the tracks on a "deluxe edition" of In Through the Out Door by Led Zeppelin, 7 tracks that are rough mixes - not the original versions found on the record that was originally released.
They have parts that are slightly different or parts that are louder/softer. It occurred to me a moment ago that for young people that are maybe checking out Led Zepplin for the first time, they're not hearing the optimal, "official" version presented to me when I was a child. They're hearing a strange version. They may not even listen to the "real "versions of these songs, much less the album experience in order.
Curiously, a side effect of this "deluxe edition", or live bias is that it affects the classic bands more than others because they're the ones that have these extra tracks presented to the listener. Which, don't get me wrong, I love - I'm listening to an alternate mix of my favorite Zeppelin song "Carouselambra" right now - BUT, I remember the first time I heard this album all the way through and thinking about how this song sat in the middle of a record with a lot of songs I didn't care for. Meaning, it told me "these guys have musical influences I don't care for, this percentage maybe", and also that there is a certain breadth and depth to an artist's muse.
I fully understood as a pre-teen musicians made music from influences, and the process is not a level, flat plane. I'm not saying people should have to listen to what they don't want to, I'm just saying this is an aspect that is gone: you don't really know what Led Zeppelin is about just because you listened to "Stairway to Heaven" and "Whole Lotta Love". And even though you may not like the whole catalog (I don't - and I'd suggest I'm a huge Zeppelin fan) you understand what their CONTEXT is about.
CONTEXT is something that has been thrown away in modern communication. It's deemed not necessary, inconsequential. Slows you down, not needed. Which is fallacious idiocy.
So, there was a period when Napster took over and IPods were the defacto way people listened to music, and people at that time that considered themselves "fans of music" went to the trouble of seeking out these alternate mixes, or strange music, or niche music. It wasn't super easy, they had to go online, search on Napster, wait.. maybe one day something would be there and not the next. BUT - the most common, "accepted" versions for the most part (with some notable exceptions) would rise to the top.
Not the live version of a Jimi Hendrix song from some oddball show, or an alternate mix. I believe this is the fault of corporate influence putting newer releases ahead of the queue, thinking it will make sales of physical media happen. A kid that thinks he likes Led Zeppelin searches for a Zeppelin song and takes the one at the top, and it's a crazy live version, or a mix without the vocal: "I don't like this" maybe he thinks, goes to something else.
What a horrible experience. The music industry has been upended so many different ways. Napster/MP3 technology started it, but at least the people that should be music fans got a proper exposure to the right examples of what they were looking for, for the most part. Chaos theory is all about initial conditions affecting an outcome; the initial conditions for being a music fan in the 21st century has been damped, if not completely wrecked.
