Deezer is by far the best music streaming app I've used. Whatever way they've put together their algorithm... It's gets me... Gives me music I enjoy and pisses me off less than any other service. Also the app is a pleasure to use
I had Spotify for a bit and got rid of it fairly quickly... It was obvious to me that they were just pushing music to me to maximise their revenue, it gave me popular ****e that I'd never listen to.
I use YouTube Music at the moment, because with it, I get add free video streaming. It's grand, but doesn't match Deezer.
