strange behavior with apple Sound Check and normalize volume off

[gaiastar]

Hi
I have bought an album via apple store , and i have played with musicbee last version , and it did play with a low volume , i have checked the preferences and normalize of tracks with replaygain tags was off
I used tag inspector to check it
I have tried to play with foobar2000 and it does play loud "normally"

I removed the soundcheck tag and musicbee did play all the song loud

my question is does musicbee apply apple soundcheck tag even normalize of tracks with replaygain tags is off ?
can somebody give a short test?
thanks
