I've measured the LUFS on a handful of songs on the Spotify desktop app using the Loudness plugin in Logic and also Izotope's Insight 2, and they are reading at -10LUFS, -12LUFS etc - see attached screenshot. I thought Spotify would normalize them to -14LUFS? I also have the 'Normalize Volume' option ticked in my Spotify Preferences. Can you please confirm if this is true? Why are the songs louder than -14LUFS? I'm in the process of mastering my own album and have been aiming for -14LUFS, assuming Spotify would normalize it if it's louder. Thanks!
