Hi Anja, what I mean is that You can't conect and reproduce the music directly in the Deezer app to a hi-fi speakers like Denon Heos speakers. To conect you need go to the Denon app and transmit the music. In the spotify app un more easy, You only turn on the app and click below, find the speaker and thas it.! Why You cant do that with Deezer.? Download the “Spotify App” onto your Android or iOS device beforehand. To play a Spotify track in this unit, you need to register in the Spotify premium account first. Connect the Wi-Fi settings of the iOS or Android device in the same network as this unit. We are happy to announce the release of the Marantz Remote App for Android! The beautiful interface and intuitive layout offer a fun and simple way to control your Marantz network product. Adjust the basic functions of your Marantz product with power, volume, input and surround mode selection. Marantz disc player control is also available via Marantz Remote Terminals (D-BUS, RC-5) connection. Everytime I use the Spotify part of Denon Remote app and a list of something is shown (tracks, artists, albums, playlists) it shuffles everything around while I'm looking at it. It's like looking at a puzzle where the pieces constantly shifts places. It's making the Spotify completely useless on the Denon Remote app.

Is it time to ditch your AV receiver remote in favor of using your smartphones? This is becoming a reality as Onkyo, Denon, Sony and many others offer Apple and Android apps that allow you to use your tablet or smartphone as a remote control. The reality, although not apparent to many, is that smartphone apps are generally better at things like navigating digital music sources and controlling multi-zone playback. The only time you really need your receiver’s remote is during the initial setup phase, or all you ever do is watching a movie from start to finish and adjust volume levels.
Denon Remote App
If, on the other hand, you wanted to listen to Spotify or Pandora, remote apps offer more intuitive and much quicker navigation. Using the hard-button remote is laborious in comparison when you need to scroll through lists of artists, albums, genres, etc. With the app you can simply tap the content you want to listen to. For example the Denon remote app has 8 short-cut buttons that are fully customizable to allow you to choose the look and function to suit your taste and needs. How it works is that once the app is installed on your smartphone, it sends remote control signals via WiFi in your home network.
Owners of 2009, 2010, 2011, or later Onkyo network home theater receivers can use the Onkyo Remote Control App to access a variety of functions, including volume, radio tuning, input selection, and other functions.
