They tend to loop rapidly, but the team had to do more with less in those cases. Chiefly, something like this:
BN3 headquarters, https://www.youtube.com/watch?v=1_CKETfEKpk
It loops in thirty seconds which is objectively terrible, but it really works in-game. Another off the top of my head like this is BN2's boss theme.
Other favorites off the top of my head:
SF3 not-headquarters, https://www.youtube.com/watch?v=tWxYgq6u0G8
BN6 dungeon, https://www.youtube.com/watch?v=_uamJI_3-9c
BN5 final dungeon, https://www.youtube.com/watch?v=5OBVju07d-o
