I checked it out for fun. They'll send you a report if you give them an email address & select  'Want More Detail'
I master my tracks around -14 LUFS,  here's a  result I got back for example.

• YouTube: --
• Spotify: -0.2
• TIDAL: --
• Pandora: +0.3
• iTunes: -2

I tunes turned you down 2db?

That sounds about right, iTunes radio is -16 LUFS.

That's a pretty cool tool. Thanks

If you use an aggregator (or whatever they're called, such as CD Baby) to be the distribution point for your files, how do you get a proper-loudness file to each of the streaming services?  Perhaps a better question is, how would you recommend delivering the proper song file to each of the services?
 
Thanks.

one of the most bad@ss albums i've heard this year,
is queens of the stone age's 'villains'
 
comes out at like a dr of 5!
 
 
LOL
 
they don't care.
they sell millions of albums,
somehow, 
they get stellar sounding mixes that sound good even when utoob turns them down by 5.6db!!!!
5.6!!
that's almost half of their original level.
 
and still it sounds kick ba!!s,
so i'll tell you this:
 
quit worrying about your levels.
worry about how good your mixes sound.

It's not a bad tool to test with,
 

• -- YouTube

• +0.1 Spotify

• -- TIDAL

• +0.2 Pandora

• +0 iTunes

See, that's why I don't master my own music.

if utoob turns down to -14,
and the DR measurement on 'the evil has landed' (the one i measured) is DR5,
and utoob turned it down by -5.6 db (the nerds measurement)
then they uploaded as a -8.4
 
and i have the disc, so i can measure directly,
but the point it......

You can go right up to the redline on a CD, and they are usually mastered louder than compressed formats. That means they're not a good reference point if you're seeing where you're at for online distributions. 
 
For example, compare this video that (probably) was prepared specifically for online use, against the CD version:

 
Right-click on the video and select "Stats for nerds". It'll show you the volume compensation being applied. It reads "content loudness" but is actually the ratio of the material's loudness to YouTube's standard. You want to see a small negative number there. In the case of the above example, it shows -2.2 dB, meaning YT automatically turned it up by 2.2 dB. Also note how good the video sounds.
 
By contrast, the album version comes in at -9.8 LUFS. Had they simply transferred the CD mix to YouTube, YT would have turned it down by 4 dB instead of turning it up by 2.2 dB.
