Why Does My Song Sound Quiet After Distribution?
Published · updated · by Loopin
If a song sounds quieter on Spotify than it did on your own system, it's almost always loudness normalisation doing exactly what it's designed to do — not something broken in the distribution process.
What normalisation actually does
Every major streaming platform turns tracks down to a consistent target loudness — roughly −14 LUFS for Spotify — so listeners don't have to adjust volume between songs from different releases. A track mastered louder than that gets turned down on playback; one mastered quieter gets left mostly alone or turned up slightly, depending on the platform.
This means an aggressively loud master doesn't actually play back louder than a well-mastered quieter one — the platform equalises them. Chasing extra loudness beyond the normalisation target buys you nothing except reduced dynamic range.
The real problem: relative loudness, not absolute
The complaint usually isn't that a track is quiet in isolation — it's that it sounds quiet next to other songs in a playlist. If your master is mixed and mastered properly at the platform's target loudness, it should sit at a similar perceived level to everything around it, even after normalisation.
If it still sounds noticeably quieter than neighboring tracks, the issue is more likely tonal balance — a lack of presence or punch — than raw loudness, since normalisation should have equalised the level itself.
Check what LUFS you actually delivered
Look back at your master's integrated LUFS reading before distribution. If it's significantly quieter than roughly −14 LUFS — say, −20 or lower — some platforms will turn it up to compensate, but not all normalisation implementations handle upward adjustment the same way, which can leave a genuinely under-mastered track sounding thinner than it should.
A master close to the platform's target loudness, rather than dramatically under or over it, gives normalisation the least work to do and the most predictable result.
Different platforms normalise differently
Spotify, Apple Music, YouTube Music and TikTok don't all target the exact same loudness, and some let listeners toggle normalisation on or off in settings. A track that sounds right on one platform can sound subtly different on another purely because of these differences, not because anything about the file changed.
This is expected and not something you can fully control from the mastering side — getting close to a common target like −14 LUFS is the practical best you can do across the board.
What to actually check before assuming it's broken
Compare your track's Spotify stream directly against a few playlist neighbors at the same relative volume setting on your device. If it genuinely sounds quieter or thinner in that direct comparison, it's worth a fresh master targeting −14 LUFS with attention to tonal balance, not just loudness.
If it sounds comparable in that test, what you're likely hearing is normal variation between platforms or devices, not an actual problem with the release.
Frequently asked questions
Why does my song sound quieter on Spotify than on my computer?
Spotify normalises playback loudness to roughly -14 LUFS. A track mastered louder than that gets turned down on playback -- this is expected behavior, not a distribution error.
Does mastering louder make my song play back louder on streaming?
No. Platforms normalise to a target loudness, so an aggressively loud master gets turned down to match everything else. Mastering louder than the target only costs dynamic range, not perceived volume.
What LUFS should I master to so my song doesn't sound quiet after distribution?
Aim close to -14 LUFS integrated, which is near what most major platforms normalise to. This gives normalisation the least work to do and produces the most predictable, consistent result across platforms.
