replay gain doesn't seem to work for me

hi, thanks for the response but i’m either a) no clearer or b) it isn’t working the way you say.

for example, if i pick one song off of Back In Black, say Hells Bells, then i pick Replay Gain, Album Mode, i would expect that all 10 songs on Back In Black to have a volume boost.

but i would NOT expect my entire music collection, hundreds of albums, to have the same boost.

is this how it should work? if so, it’s buggy.

when i choose Album Mode for one song, it’s then automatically applied to every song, every album, in my entire collection.

is my understanding wrong? or is it a bug? i’m a Mac user, BTW.

thanks.
