I am on macOS Big Sur, and am directly using Plexamp 3.4.7. Also to be clear, I am looking for per song boosts though I do not create Albums from various tracks, I just use Albums directly as the recording media had dictated. While loudness leveling is useful, it would be even better to have the per song playback ReplayGain respected. All of my files are FLAC and always 44.1/16bit or higher.
I will also say that playing my music on Plex itself is a horrible and quiet experience, whereas Plexamp is closer to what I would expect the playback to sound like. Still not what I would get in iTunes or FuBar2000.
