That’s because Dark Side of the Moon is a single track 🙃

Concept albums are meant to be listened in their entirety so it makes sense. Pink Floyd is a band notorious for concept albums, but they’re not the only ones. If you’re an Arctic Monkeys fan, you’ll probably not listen to just one song from Tranquility Base Hotel & Casino. In spotify which shows the number of listens per song, it shows that all songs on Tranquility Base have the same number of listens (some more than others, but not by an order of magnitude).

I guess OP was mostly talking about regular albums which are mostly just collections of disjoint songs. It’s probably happening less now that people consume music one song at a time, but there are numerous examples of artists releasing one good song and then a bunch of filling around it and pass it as an album. If you were playing a CD (or a cassette if you’re old enough), chances are you’d listen to the rest of the album anyway and eventually like it through repetition. For example, with spotify again, if I’m looking at Cowboy Carter by Beyonce, “Texas Hold’em” has 340 million listens and all the rest are below 20 thousands.

I just can’t be bothered listening to tracks I don’t like, especially in this day and age where I don’t have to swap CDs/tapes to listen to a track from a different artist.

Meanwhile me with only Money and Another Brick in the Wall as the only Pink Floyd tracks in the whole digital library
