Meaning of "One Thing" by Runrig

The lyrics of "One Thing" by Runrig explore the futility of trying to salvage a broken relationship. The narrator presents various scenarios where decisions could be made - to walk away, to confront fears, to question faith, to share secrets - but ultimately concludes that none of these actions will alter the inevitable outcome. The repetition of "It's not going to change a thing" emphasizes the resignation and acceptance of the situation. The imagery of a painted picture with bold colors representing different life seasons suggests that the story of the relationship has already been told and no further attempts to alter it will make a difference. The lyrics convey a sense of inevitability and acceptance of the end of the relationship, regardless of any efforts made.
