Most of them are either glorified Spotify playlists or subscription traps that gate basic features behind a paywall. And the "binaural beats" ones — I dug into the research and found that the evidence for binaural beats is actually pretty weak (only 5 of 14 studies in...
BraintunesFocus music that uses real neuroscience, not binaural beats
