Before the UI change when you created a playlist from an album the default name would be "Album name - Artist name" (at some point in the past, it used to be "Artist name - Album name" which I liked even more, but I can live with the other option as well).
When the new UI was introduced this was broken for a while and didn't generate a name at all anymore. It has been fixed recently but now only includes the album name. Please change it to how it was before so that the artist name is at least somewhere generated!
Since Spotify doesn't allow selecting and copying text inside the app it is otherwise impossible to get an artist's names for manually organizing your library expect typing it by hand.
