The sentiment at the end of the article
Logistically and promotionally, batch-releasing makes sense. But part of it might be the elemental appeal of the format.
makes sense to me. My uneducated guess would be that for pop music that's meant for radio/youtube/movies, releasing albums will make less and less sense. For "artists" like a lot of rappers and independent bands, there's an "elemental appeal" to the album format, that'll probably be around for a long time. Especially so because that's where monetization has traditionally been. Once there are more iron-clad ways to monetize from youtube, spotify, and soundcloud, I would guess that more musicians will release one-offs or smaller groups of songs.
