Btw. I tested my own music.

First I played inside songs from other people a Ralf-mastering of my own
music.

Most people didn't like my song.

Some weeks later I played the same song inside other songs from other
people by a loudness-war-mastering.

Most people liked the song.

Playing the same song two times can't be called heavy rotation, hence
they were not accustomed to my song, but they need a bad mastering to be
fine with this song.

A blind study is useless regarding to musical issues.

Or do you think we should start mixing music optimised to loudness,
because tests show that the audience prefers music without dynamic?
