Every episode of Andor has a slight variation either melodically, tonally, or instrumentally in the way the opening theme is played as the letters come into view. I have yet to understand or link it to anything significant, but it must be intentional
Continuing on the Andor soundtrack beyond the opening theme, there was a callback in ep7 (spoilers below)
The soundtrack of space Miami was the EDM song, Niamos! (Morlana Club Mix).
It was the same song that played in the club on Morlana One in ep1 of Andor, though it went uncredited in that episode. In both cases, this song was used as part of setting up a "people in law enforcement are dangerous bullies" scene.
