Delete Song from any playlist - Remove song from any playlist

[maphead]

ALL I want to know is how - in simple terms - to delete ANY song from ANY playlist. 

Tell me please where to find and how to execute that action on each 'style' of Spotify....(MAC/iOS)

On the mac, right click a song and click "delete" in the option menu. Or click on a song and press delete on your keyboard.

For iOS:

In the top right corner of a playlist, click on the "..." button and then click on "edit".

You can then scroll through the playlist and remove the song from the playlist.
