Netflix
Spotify
Hulu
Netflix has always been pretty great with movie selection, most of the original shows are decent. Hulu has some good content, but I'm very selective when it comes to the original shows (like Castle Rock, Mr. Inbetween, and The Act). Spotify is a fine way to stream albums and newly released music, but I listen to mostly underground music that is free on SoundCloud/YouTube, so I don't use it much.
I don't pay for these services personally, but my sister does, so I just leech off of her accounts when a good movie or show gets released lol. I'm totally content with not using any streaming services, because I'd rather spend my entertainment time reading good books or playing story-driven videogames.
However, HBO Now and Amazon Prime are very tempting, but few people invest in them as daily-drivers. Likewise, never bought into PS+ or other popular gaming services like that. I don't see the long-term appeal in services that only offer like 2 good shows/games to watch/play every month.
