I have an album from a few years ago on streaming services that was mastered to about -9 on the LUFS scale. It sounds nice and loud on SoundCloud, which doesn’t do any normalization, but on Spotify, the normalization algorithm turns it down enough that it sounds noticeably softer than music by other electronic artists (although some of that probably comes down to my mixing skills versus those of experienced recording engineers). Spotify used to normalize to -11 LUFS, but more recently has migrated to -14, which other streaming services already use and seems to be becoming the standard. For my new album that was just released, I mastered to about -11 to -13 LUFS, which tends to be loud enough to still stand out un-normalized, but is close enough to target that it doesn’t take a noticeable hit on normalization.
