I think the other tracks use official English translations that we already know, but you're free to check when you get the chance. A quick one would be at the very beginning. 40 seconds after the first title card, we see this shot:
I'm pretty sure there's a good shot of the score at least a couple times during each track. At 1080p quality, the titles should be clear enough to read. (and I'm assuming the Blu-ray uses the same footage as the Niconico stream)
