I just noticed today on Spotify for Windows that there are two very similar options in Settings. In the Music quality section, there is a "Normalize volume - Set the same volume level for all tracks" option. And in the Playback section (which is in the Advanced Settings), there is a "Set the same volume level for all songs" option. Each can be turned off and on independently. What do each of these options do, and what is the difference between them? I couldn't find anything about this on the web. Thank you!
