I have spotify, which is always good.
There is an app called swipefy, I think I pay around $8 a year for it but it allows me to discover new music that I may not have noticed before.
What do other people have that they feel is worth it? I feel like since I have spotify I don’t need things like amazon music or youtube music, or pandora plus.
But apps like swipefy which allow me to discover new music are always good.
Just Spotify as a paid app. It does a reasonable job of recommending songs and, more importantly, songs that I do want to listen to are almost always available. The scant few that aren’t usually aren’t available elsewhere on a streaming service either. YMMV based on your taste in music.
I used to use Pandora way back when but it was much worse at recommending stuff (usually the same batch of songs) and had worse randomization (which is saying something ‘cause Spotify is no gold standard). I never got into Youtube music since the free version wouldn’t allow me to turn off my phone screen and that was just stupid so my testing of it ended nearly immediately. No idea if that’s changed since; haven’t had a reason to try again.
Never dabbled with Deezer and other smaller apps. I think once I was putting in obscure tracks off Spotify into Deezer and the success rate wasn’t high enough to bother testing a switch.
I pay extra to Amazon to be able to access some music. It’s pretty cheap, but is part of Amazon’s nickel-and-dime you to death philosophy.
I’ve been happy with Spotify and I have two other people on my account. No noticeable issue from anyone. It let’s you download songs and play them offline for a month, never seems to hang up and works in multiple foreign countries the world over.
But still I am paying like $21 a month which seems like a lot for a streaming service, but then I recall that I used to spend much more than that back in the day when I was poor on albums, CDs, iTunes and such things as Columbia House/BMG music. Still I have YouTube premium and I keep getting tempted to try it out but I don’t for some reason. I guess it isn’t broke and has not pissed me off enough to bother. 
Spotify and AllMusic.com.
Both are worth it to me.
mmm
ETA: AllMusic is a subscription, but not a streaming service, which is maybe what you were asking for.
I don’t have any paid subscriptions. Generally if I think of a song I want to hear I just find it on YouTube. Which with ublock enabled is ad-free.
On the other hand, YouTube’s recommendations are rather predictable.
I imagine a service might have its uses to provide suggestions for things one hasn’t otherwise encountered, though?
Question for members: If you use any service, is it primarily as as a delivery method, or a discovery method?
It’s very subjective but I have always preferred YouTube Music (previously Google Play) over all of the other music streamers. As a bonus you get YouTube Premium packaged with it for the same price (not YouTube TV, it’s YT without commercials). Plus I get 30% off of that bundled with my cell phone.
