I don't think Spotify has a specific word for it, just "Normalize volume", with an option to set it to quiet, normal or loud. There's a clear difference between well-produced songs and over-compressed songs. The over-compressed ones tend to be much quieter, because the normalizer goes by average volume instead of peaks. So well-produced songs get to go "over" for some amount of the song, to give room for dynamics.
