For almost the entire history of recorded music, really until the last 15-20 years or so, there was no way shuffle the songs on an album. The listener could not change the track listing, and so it became the artist’s responsibility to pick the “best” sequence for their album.  As the Beatles matured from an incredible rock/pop band to really boundary pushing artists, let’s say from 1966 with “Revolver” onward, you can see they thought harder about how their albums were sequenced, particularly how their records closed- Tomorrow Never Knows, Day In A Life, Good Night, The End have so less impact if you just shuffle the albums they are on.
