If you don't like it, that's cool, but you're really not giving it credit for what it is. Poem is the only consistent tracks between Persona games, and this is a battle arrangement of that, which makes it pretty significant as it is. Then you consider that the song changes style, going from rock, to electronic, to classical. You know what soundtrack combined those three styles? Persona 3.
It's a culmination of everything that's come before it and an acknowledgement of the series as a whole, whilst recognising the direction that the series would take. Even if you don't like it, it is significant.
Those two tracks are awful.
