Correct! For example the Jewish musical tradition is extensively minor, even the happiest of songs. Think of Hava Nagila. Musically, that's as minor as it gets - but it literally translates to "Let's Celebrate" and it's traditionally a party song sung by large groups at weddings.

Besides Jewish music, there is also a lot of other Balkan / Eastern European music that has this "reversed" rule and uses minor in ways that aren't meant to imply anything negative emotionally.
