I'm Deeazer Premium member for almost 2 years and i use it on several devices. I've nothing to say about the quality of the music and library, is really great but there are a couple of annoing things. Starting from the search box, when u search a song there's nothing that show in which playlist this song is included, this could be a very usefully things, spotify already do this. With the new release of the app for smart tv u can not filter anymore by genre, all the section related to the category disappered. Last but not least, as opposed to spotify, if u have an apple watch with cellular plan u can not listening the music around without your smartphone. This is a really annoing things in particular when u go out for a run. i'll probably move to spotify.
