We are the 432hz community, there’s an app, called 432Player, that successfully integrated the Spotify SDK with their app in order to play the music in the 432hz tuning (a tiny but significant difference for us), which is the we enjoy consuming music.
We understand that this is a niche and not too many people around the world are in need of this feature and thus No Need to add this to the original Spotify app. Therefore all we (the 432hz community) are kindly asking is Please grant the developers of the 432player app who Already SUCCEEDED in doing this the approval to go ahead and publish the app for us so we can all enjoy Spotify in our highest form.
We know they were in contact with you but eventually they didn’t get an approval, but we are hoping that if you see enough of us who truly want this you might consider allowing one more time for an app of this nature to integrate with Spotify.
We understand that Spotify presents tracks as they are meant to be heard by the Artist. As such, Spotify won't implement a feature that would change the tuning of a song for them - as this would go against how they intended their music to be presented.
With that said no artist in any field can control how an audience perceives and experiences their content, whether thats through special headphones, an external music equaliser, pitch shifter or any other circumstance.
