I really hate that you were downvoted for this. It may be only a single sentence, but I think you're correct to bring up the fact that Spotify and Apple Music both don't represent the entire music industry. These two entities are merely soulless peddlers of the Big 5. There are substantially important pockets of the music industry that do not exist in this narrow realm.
You know for a fact that the only reason either of these music services exist is because the Big 5 are in on it. Their catalog is what carries the services, and is what makes them profitable.
There is no Spotify or Apple Music without the Big 5. You cannot say the same of Bandcamp.
Why is that a bad thing? It's a positive that the big 5 are enabling smaller artists labels to have distribution to new listeners.
I love Bandcamp for downloading WAV files for DJ purposes but as a streaming service, it just isn't that great simply because of the lack of breadth of the catalogue.
