Thank you!
It's not totally intentional, but it's something I put lower priority on editing because there is a bit of this feel like Thorin and company are just ad hoc singing these songs, rather than preparing them, in the warrior poet tradition. My goal with these is to make it feel like you're there in person. It seems likely to me that this is the intention because Tolkien uses many of the lyrics over again with slight variations, as if people are forgetting the exact words and not really writing it, as is reflected in reality as well.
