What you say is still true of the Amazon and Apple offerings, though. Haven't tried Youtube Music, so can't comment on that.

It's virtually all popular music recently published commercially in the world.
It's missing large portions of bootlegs, old music, foreign music, radio shows, mixtapes and live streaming music to list a few prominent categories from music in my private archive of cultural works. Those categories, btw, are well represented by torrents on tracker sites.
One of them has come back recently. It's still listed as by the wrong artist (same name, but dead, vs. the active artist who actually performed it) but I'm not reporting it again because I suspect I may have made it disappear for a couple of years in doing so before.
It's kind of crap and disorganised after anything more than barely glancing at it really, must be infuriating for (or just not used by) people who actually are into it.
Until they decide to silence the artist you want to listen to because emperor god trump decides to unperson them.
Putting what music you listen to in the hands of a US corporation is such a dangerously stupid idea that it is amazing to me that there are people here who are OK with it.
>I think Spotify wins over pirating because of its relatively low cost and convenience
Spotify isn't "convenient" if you want to control and understand the media and software in your life. https://www.defectivebydesign.org/spotify
Thankfully Spotify isn't primarily a U.S company.
To get access to "all" TV content legally would be hundreds of dollars a month. And for many movies you must buy/rent each individually. And legal TV and movies are much more encumbered by DRM and lock in, limiting the way you can view them. (like many streaming apps removing AirPlay support, or limiting you to 720p in some browsers)
I think Spotify wins over pirating because of its relatively low cost and convenience. Pirating TV/Movies have increased as the cost to access them has.
