When I put up the split of songs to show how I translated it differently between Urai and Kakizawa's, I got a strike. I appealed it by saying it was for educational or critical purposes, and I think I had a pretty good argument for that since it was posted split up rather than full songs, and in the context of questioning translation choices vis a vis actor delivery of the same text line.

This was when the musical was still very fresh. Not sure if they'll be as aggressive about copyright now.
