Fairly good. Pinkie wrote a song bad enough to cause a war, which is impressive, even for her.
My main complaint with this one is that they really trivialize the buffaloes' position on the issue. The settlers get to say "we must do this or our families will starve" and the buffaloes just say "we were here first, so screw you." Of course, it's only really 'trivializing' because this is an obvious stand-in for the dispute between native Americans and the settlers, which had a bit more going on. Like Bridle Gossip, when handling sensitive issues in a kids' show, things can go a bit wrong due to the simplification needed.
