Deezer on Android TV or Google TV should have the option to either:
- Switch accounts in app. For example, independent family accounts have multiple accounts in 1 family. Ideally you can sign in multiple accounts into the app, and then switch accounts in the app.
- Best option: make signed-in account dependent on the current profile in use. Google TV (At least version 14 on the Google TV Streamer) has the option to have multiple profiles (like, you can add your Google account and it will show up as a profile, with different recommendations as the others, and signed in to the YouTube app in the respective account you selected in the profile selector). This would be the best option, because it would allow each person to quickly select their own account and would prevent other users to access your account from their profile.
Either option would solve this problem.
I hope to see this in the Deezer for Android TV app someday.
