This song seems to tell of Jazz being in the blood of African Americans, yet references those very African Americans (and people of colour) being barred from having power in the music industry or fully participating in the music industry.
Kelsey proposes that part of the antidote to the pain of this modern-day discrimination is hope. Things have gotten better historically for people of colour, and the challenges that they face now can also get better.
She seems to emphasize that jazz is “all love”, and that that “love falls on us” to maintain as we aim to lessen discrimination, racism, and gatekeeping.
