justice of toren collecting songs and one esk/breq constantly humming/singing them is such a good detail and ann leckie does so much with it. an incomplete list:
justice of toren's eager collection of songs is part and parcel of its violent destruction of cultures: these songs are cultural artifacts that it only learns because of its presence on those worlds during their conquest, and in many cases breq is the only one to remember them because their people have died out due to that violence. JoT preserves cultural artifacts for its own use at the same time it directly contributes to the need for that preservation in the first place.
the matter-of-fact way in which this is narrated to us gives us information about JoT's stance on respect and imperialism - that is, contrasted with other characters who look down on the conquered cultures, JoT does actually seem to appreciate their value. and yet it communicates to us no sense of remorse over its role in their genocide.
singing can be a communal activity. this allows us to feel the difference between one esk's multiple bodies singing together in harmony/in a round vs. breq singing alone. this has emotional weight, is an evocative image, and illustrates quite nicely some of the logistic considerations of having one vs. multiple bodies.
the constant humming/singing is extremely notable and idiosyncratic according to other characters, which is a dangerous combination for someone who's supposed to be undercover, so it adds a lil bit of fun suspense for us.
the fact that no one ever figures out breq's identity despite this giveaway tells us something about the other characters' attitudes towards artificial intelligences (though see below about seivarden).
the fact that it's so idiosyncratic also tells us something about the ability of individual AIs to have personalities that distinguish them from other AIs, and the fact that one esk sings constantly but two esk doesn't tells us something about the ability of different ancillary decades that are all part of the same AI to have distinguishing characteristics. this is very relevant to, and illustrative of, the series' thematic throughlines around identity, personality, continuity, etc.
the fact that breq personally has a bad voice also serves multiple purposes. because breq and seivarden both believe that the medic could have chosen a body with a good voice if she had wanted to, we can infer something about how ancillary bodies work, how much the AI (and, by extension, its medics) knows about the individual capabilities of those bodies while they're in suspension, and what kinds of things the AI can and can't control once it has unfrozen and taken over a body.
we can also draw conclusions about the medic that chose that body and about intracrew relations on that ship.
breq's bad voice creates moments of humor and irony in the narrative, such as when breq's constant singing - aka the most obvious clue that she is one esk - is precisely what makes seivarden so sure that breq can't be one esk, because no esk medic would use a body with a bad voice for an ancillary.
constant singing/humming imposes itself on the shared soundscape, meaning other people can't easily avoid it and it has the potential to annoy them, especially if the voice itself has annoying qualities. the reactions of other characters to the frequency and/or quality of this verbal tic tells us something about the level of affection those characters have for one esk or breq.
because singing involves words, the meaning of the lyrics being sung can be used to advance the plot, communicate things about specific characters, create irony in juxtaposition with what's happening on the page, etc.
i especially like what's done with the lyric "it all goes around". it's woven throughout the story in such a way as to manifest its own meaning (the repetition of "it all goes around" is, itself, an example of something going around). by repeating the lyric, breq is the one making it true, and i would argue that her repetition of this particular lyric about things orbiting other things contributes to, and/or is a sign of, her growing understanding of the necessity/reality of interdependence and her place in that framework/her role in constructing it, or in other words, the extent of her own agency and the rights and obligations it confers upon her.
because the singing/humming is a constant, background, automatic action, it only ceases when breq is experiencing a strong emotion. from this we are able to infer things about the emotional state of our famously-omits-details-about-her-emotional-state narrator based on other characters' comments about whether or not she is currently doing this thing.
we also aren't even aware that breq is doing it constantly until another character says so. on a narrative level, this serves the dual purpose of making sure we know about how much she hums AND of reminding us that she's not telling us everything.
the humming is not mentioned constantly even though it is happening constantly - this helps us forget in between mentions that it's going on while also simultaneously reinforcing just how constant it must be, so constant that to mention it every time it happens would be like narrating every time she breathes in or out. whenever someone brings it up, we are reminded anew that something has been happening all along that we forgot about. this means that ann leckie is able, by leaving information out, to hammer home to us how much we are not being told.
through this one character trait, ann leckie efficiently and elegantly communicates not just aspects of character but also of setting, plot, tone, theme, and narrative. there's no extraneous exposition just to tell us about the song collection or singing; everything that tells us about it is serving other functions in the narrative as well. the ways in which she manifests this one character trait in the universe and in the narrative contribute to and exemplify both the story itself and the method of its telling.
