Personally I think that Deezer's discover options are good as they are, and better than Spotify :)
I agree (especially now with the new Flow), but having something similar to Release Radar (Spotify) would be very useful. Another way to achieve that it could be to have a list of new releases from the artists we love.
Yes please! @Rafael, I can't find flow tabs, are they only available after a certain period of time? I can only access flow at the moment and it has so far been a so-so experience (I take it it may learn over time).
