That is still an example of knowing the content that you want to play exactly, you just don't remember its official name - and yes, search engines have gotten pretty good at this. The more relevant use case is "hmm, I'd like to listen to some prog rock, let me browse what Spotify has and see what takes my fancy". Sure, I could say "VA, play prog rock", but I don't want it to choose for me: I want to browse the available content to remind myself what are my options, and choose one when I see one that looks interesting.
