I think people have neglected the lyric "...with nothing wrong".
This to me speaks to a child with a sibling who is sick or disabled (the subject of the song is the child with "nothing wrong", which could be used as a descriptor to differentiate the child from a child with something wrong).
In that scenario, her parents, sibling and other adults could be preoccupied with the ill/disabled child, and thus the other little girl craves attention, but doesn't get it "She'll sing her song to anyone who comes along". Even though there's "nothing wrong" with her, she's "all alone".

Just my 2 cents.
