I suspect that the pressure to fill "a whole album" has diminished as recorded music publication has shifted largely toward digital distribution, and especially streaming.
I don't think that prohibiting the publication of whole full-length albums would be a good idea. There have been plenty of great albums, that really deserved to be whole albums. Maybe usually that's not the case, but still, I wouldn't want to prohibit the album construct.
If artists would be forced to release only singles they would be pressured to make every song fit the “hit” format. Music would be more homogenous and boring. I doubt Bohemian Rhapsody would ever be released in such a world.
I guess I’m in the minority but I like listening to full albums even when using a streaming service.
No, some of the best albums ever were all written around a common theme. Having nothing but a collection of singles makes it hard for artists to commit to a subgenre for a while without making it their identity. I think Pink Floyd is the best example of this (the large difference between Dark Side of the Moon and The Wall) or perhaps any album written by David Bowie (where his albums experimented with characters or identities such as Ziggy Stardust and the Thin White Duke, in conjunction with new sounds) but My Chemical Romance is a more contemporary example (for me, anyways), with Welcome to the Black Parade standing in contrast to Danger Days. I don't listen to Taylor Swift, but she's supposedly remade her identity around each new album release (or what her fans call Eras)
