Yes, though a radio station would often times start with an intro and let the record play through the next track (speaking as a child of the 70's when progressive rock / concept albums were at their peak). DJs & programming directors knew that certain tracks would not make sense on their own and would adjust.

I have a hunch that it's not streaming that's really responsible, per se, but the "Shuffle" function that's been available since the CD player. I tend to have a large playlist and more often than not, I set it to shuffle the tracks. But I did essentially the same thing when I had a 60 CD changer years ago, too. I think this trend probably started there, accelerated when MP3s and ripped CDs became popular (prior to steaming services) and streaming is just the next step in that progression.

The way we consume other media is likely to part of this as well, so saying it's streaming is perhaps a bit of a stretch even if streaming makes it possible to jump more easily.

(for the record I have not read the article, though I scanned it to be sure they were talking about streaming services).

Queen's "We Will Rock You"/"We Are The Champions", Boston's "Foreplay"/"Long Time", and Alan Parsons Project's "Sirius"/"Eye in the Sky" are examples of this. It's almost strange to only hear one half of the pair, and in the case of Foreplay and Sirius, those are completely instrumental.

Good radio stations still honor these unwritten requirements.

Also, "Eruption"/"Running with the Devil", too.

SiriusXM's Beatles channel plays pairs of songs together when that is the norm on the radio. Some White Album songs basically lead into each other, iirc.
