It's not fair you're being down voted, because you're absolutely right. I subscribe to both Tidal and Spotify, and Tidal has vastly better quality music (plus a bunch of artists that are not on Spotify...).

If people are listening through some 'Beats by Dr Dre', or Airpods ,or linking to a bluetooth speaker, Spotify is fine.

If someone has a DAC and some decent headphones, or a decent hifi, you can notice the different easily, especially for certain genres. Not all music compresses well.
