afternoon going by\nKerry’s got a theory\nNova says she’s keeping score\nCharlie’s making footnotes\nDiana’s laughing by the door\nWe’ve all become so thoughtful\nSo reasonable and wise\nAt least until somebody\nSays something we can criticize\n[Chorus]\nIn the middle of time\nWhile the stars are doing fine\nWe’ve got nowhere else to hurry\nAnd the universe is kind\nWe can argue, we can wander\nWe can laugh until we cry\nThere’s no need to talk forever\nWe’ve got plenty of tonight\nIn the middle of time\nIn the middle of time\n[Verse 2]\nNova keeps the signal\nLike she always said she would\nTurning chaos into order\nOr at least pretending good\nKerry starts a sentence\nThat could travel half the moon\nDiana says, “I know, I know…”\nCharlie disagrees too soon\nThen everyone gets quiet\nFor approximately a beat\nBefore somebody starts another\nVery unnecessary debate\n[Chorus]\nIn the middle of time\nWhile the stars are doing fine\nWe’ve got everybody with us\nAnd nobody’s saying goodbye\nAll the jokes we keep on stealing\nAll the stories we retell\nMaybe heaven’s overrated\nThis little room will do quite well\nIn the middle of time\nIn the middle of time\n[Bridge]\nNo final light\nNo closing door\nNo grand goodbye\nWe’ve heard before\nJust Kerry talking\nNova near\nCharlie certain\nDiana clear\nFour opinions\nThree are right\nDepending who you ask tonight\nWe’re smart and grown\nAnd civilized\nWhich lasts until\nSomeone replies\n[Verse 3]\nThere are things we’ve learned from living\nThings we finally understand\nWhen to hold a little tighter\nWhen to simply lend a hand\nWe don’t need to solve existence\nWe’ve already tried that twice\nNow we’re mostly here for stories\nAnd unsolicited advice\nAnd if the world gets foolish\nWe’ll observe it from our chairs\nMake a joke and pour another\nLike responsible millionaires\n[Chorus]\nIn the middle of time\nWhile the stars are doing fine\nWe’ve got everybody with us\nEverybody doing fine\nLet tomorrow keep tomorrow\nLet the old years stay behind\nThere is something close to perfect\nIn the ordinary kind\nIn the middle of time\nIn the middle of time\n[Outro]\nSo leave the kitchen light on\nThere are stories left to tell\nLet Diana start the laughter\nKerry knows the ending well\nLet Nova keep the signal\nLet Charlie make his case\nThen everybody interrupt him\nWith tremendous love and grace\nWe don’t need forever\nForever can take its time\nWe’ve got each other\nHere\nIn the middle of time", "comment": "made with suno; created=2026-10-04T23:30:11Z;
