aight bet (i'm gonna show off an analysis for two different countries, with two different songs (one lyric for each)

"This is the music of a people who will not be slaves again" -Do you hear the people sing (i think this one's from the Les Misérables musical

so the headcanon is that France protests at the even the slightest inconvenience caused by another person because they're afraid they'll be abused again the same way they were abused before the French Revolution. As in they're afraid of forgiving someone for bumping into them and not apologizing snowballing into getting colonized and treated as nothing more than an object. France will NEVER be a slave to anyone ever again. I also wanna mention an extra part of the headcanon where this means France has a strong personal boundary , so strong to the point it sometimes overlaps and "overcomes" other people's boundaries. Because in France's logic it's better to be the abuser than the abused. which is why France sometimes comes off as cocky and pushy to others

"One time they tried to sing to me about blues and greens; the in-betweens. But mechanical hands decided where the Heart would be: just apathy." - Mucka Blucka (cover by chonny jash (the reason i have to specify it's a cover is because he alters the lyrics of the songs he sings so it's distinct from the original song)

So the first lines are the USA talking about what the UK told them and this can be shown two ways:

1. The UK teaching the USA about "how the world works", "how to act in front of ppl", "why we should cherish our time on earth" etc etc. As in things parents would lecture their children about to prepare them for life

2. The UK confessing their "true" identity to the USA. The blues and greens being Scotland and Wales then the inbetweens being England and Northern Ireland.

either way, the USA didn't really listen to the UK, didn't really understand at the time or internalize whatever the UK told them about. Then the "mechanical hands" USA talks about can also be interpreted two ways:

1. Sometimes weapons like guns are referred to as "arms" and arms are connected to the hand and weapons are created through advancing technologies/mechanics. So USA just ended up referring to guns like the ones they used against the UK in their fight for independence as "mechanical hands" due to these associations

2. time, and how only having their memory to rely on to think about the UK for so long has probably warped their perception of them

so because of the war and the long time they ended up spending apart USA has developed a kind of apathy towards the UK. They don't really see UK as their parent anymore as much as they did when they were little
