Loud is not a number you win
Every streaming platform normalizes playback. Pushing your master louder than that target does not make it play louder. It makes it play smaller.
What normalization actually does
Spotify, Apple Music, YouTube, and Tidal all measure your track and turn it down to a house level so the next song does not blow a listener out of their seat. If you mastered at a much hotter level, the platform lowers it and the transients you crushed to get there do not come back.
So the loudness war moved. The competition is no longer who is loudest. It is who sounds biggest after everyone gets turned down to the same place.
The number that matters more
Crest factor, the distance between your peaks and your average level, is what survives normalization. A record with room between the two sounds punchy at any playback level. A record squashed flat sounds tired at every level.
That is why a well mastered track at a moderate level sounds larger next to a brickwalled one once both get normalized. You can hear this yourself with the free song check on this site.
Clubs and cars are a different job
A club rig has real headroom and a system engineer riding the level. A master built only for streaming can feel thin there. That is what an alternate club master is for, and it is a different file, not a louder version of the same one.
Say up front where the record is going. A song built for a Miami club night and a song built for a playlist add are not the same master.
Questions about how loud should my master be
What LUFS should I target?
There is a range rather than a number, and it depends on genre and arrangement. Chasing a single value is how records get flattened.
Will a quieter master hurt my streams?
No. Platforms level everything. What hurts is a master with nothing left in it.
Can I check this myself?
Yes. Drop the file into the free song check and it reports loudness, true peak, and crest factor.
Do I need a separate club master?
Only if the record is going to a system with real headroom. Ask before mastering, not after.
