Also, I know it's a bit niche, but Deezer does not have an equivalent of "Spotify Connect" protocol, which means that Network Integrated Amplifiers (like Onkyo A-50), CANNOT implement a player with good UX. Spotify is now king since they introduced lossless quality which is enabled by default in such amplifiers. The benefit is that there is no local streaming (e.g. Bluetooth) and no latency. The data come from Spotify directly to the amplifier and then your speakers.
So, Deezer that had a audiophile target audience, has effectively lost the game.
Nitpicking but those devices do not "benefit lossless by default" after Spotify started offering it.
I was very disapointed that my Yamaha network receiver didn't get an update to support lossless from Spotify Connect.
