Thanks for the mention of the poll results and it's true that Spotify is definitely a place to have your music just because so many listen to it with a combination of the rest, whichever you prefer.
For me, I have stopped looking at Soundcloud and as the EAR releases get on your YouTube channel by default, I've shared YouTube links for full track listening on Hive if I'm doing a Hive only post (not from my website) and also Spotify links (it just looks so much better and professional if you show you're on Spotify in my experience, especially to non-savvy folks who don't produce music).
In terms of actual releasing, I get that EPs and albums are great for story telling but when it comes to consistent exposure, I release singles from the EP every 2 weeks, which gives a chance for you to submit to editorials, then release the full EP in one 2 weeks after the final single release.
One thing is for sure is that you shouldn't just rely on one avenue or stream for your music sharing but balance 3 I'd say. For me, Hive is my forte due to being here for 2 and a bit years, followed by using twitter. Then music streaming, I basically use Spotify because of it's ease of use and algorithms to search music I'd like is pretty much...well... spotless.
Not too sure about Emanate, haven't dived too much in to that yet but I am at least all set up. If they have embed players that can be used on WordPress and Hive, then we're definitely heading in the right direction!
