Numbers Dance in Perfect Line (Divisia Indexes)

[Verse] In the city we roam we chase the light Every corner turns a new delight Whispers echo in the starry night With a heartbeat that's out of sight [Chorus] The key to Divisia indexes Percent change of the sum of X and Y It's the share of X times its percent change Plus the share of Y times its percent change [Verse 2] On the edge where the shades collide We count the moments that we can't hide Symbols flicker on the other side In a dream where the rules decide [Chorus] The key to Divisia indexes Percent change of the sum of X and Y It's the share of X times its percent change Plus the share of Y times its percent change [Bridge] In the math our hearts align Every fraction sings a rhyme In the balance we all find time Numbers dance in perfect line [Chorus] The key to Divisia indexes Percent change of the sum of X and Y It's the share of X times its percent change Plus the share of Y times its percent change
