Interesting, I find the UI to be better than Spotify. Not good, but better.
For Spotify, which I’ve been a paid subscriber from basically day one, the UI went downhill from incredibly great (I do have fond memories of the first client in Qt) to a total mess without any consistency.
Tidal is just a stagnant mess. Apple Music is not better.
I guess we are just suffering from the fact that UI are not made anymore to be useful but to influence customers behaviors.
