The queen at least has way too much glee in breaking Twilight for me to think of her as non-evil, especially as she was clearly aware that she was being a bitch. I don't think the changeling morality is different to the point of
Blue and Orange Morality; it's more like
Values Dissonance than anything else. And I'm pretty sure the the "feeds off love" thing has the implication that having love removed is a bad thing. The other issue is that in order to feed off of that love, one member of the relationship gets screwed; the Queen couldn't have fed off of SA's love for Cadence without Cadence getting removed from the picture.
That said, we just don't know enough about how changeling society or biology works to say anything about society as a whole. From what we
have seen, I think it's safe to say that Chrysalis is evil, and the fact that her legions are gleefully going along with her plot makes them evil by association. Not entirely evil, or even always Chaotic Evil, but all the ones we've seen lean in that direction.
EDIT: And no more about that because conversation has apparently moved on.
As for the band thing, I think it would be amusing to have Rarity playing something totally random. Like a theremin.
