This is a general critique of the awfulness of Spotify Help and Community online resources.
Search results go back years and are typically irrelevant to a search query that always relates to a current version of Spotify.
Very few questions have answers.
There are no explanations of how Spotify actually works with regard to owned music versus Spotify licensed music, downloads, etc. For example, what happens when I tell spotify to download more songs than the 3333 limit? Are songs removed to make room for the new selections? If so, which songs? If not, how do I know my selection will not be downloaded? I could go on...
Spotify now has a sufficient user base to justify detailed videos by operating system of how the interface works.
I sure hope you upgrade your act here so I am not tempted to try another streaming service.
