One of Baba Yetu's strengths are the quiet, delicate moments, and its sense of yearning. At times you hear individual voices, while in other moments the choir dominates. I listened to BY last night after the VII theme reveal, and I woke up this morning humming the melody. There is something sticky about it.
By contrast, in the new theme "Live Gloriously", the timpani drums are banging on at 00:01. While listening to it, I am having a hard time imagining anything other than a Conquest victory. The song is epic, bellicose, and heroic. It would fit in very well in a Howard Shore epic score -- very LOTR: ROTK, in my opinion. It's very grand, very glorious, and I don't mean to be insulting to Tin or any of the contributors. However, the song mainly inspires in me the desire to burn cities to the ground.
