This is like a song for the last resort, acting vengeance upon traitors, leaving everything behind, accepting your fate, readiness to exchange your life for the better tomorrow. This is the personal experience I get from hearing this specific song and I don't even feel like I read too much into it, I'm glad the experience I get from this song doesn't fade even after years of hearing it.
" Summer is a-coming; arise, arise "
"It's ever so wrong to dare to be strong"
Maybe these visual images shaped how I feel about it:
This could even become a song for this kind of ceremony, I feel the sanctity and authenticity.
