Grammy-winning pop superstar Taylor Swift used her songs to highlight various phases of her career at the Prime Day Concert here, from starting off as a country singer to getting inspired by things around her, to an apparent dig at American entrepreneur Scooter Braun, with whom her ongoing feud is only too well known.

The live concert incidentally marked her first public appearance since she got embroiled in a battle with Braun over his purchase of Big Machine Records, a label through which she launched her career. As part of a $300-million deal, Braun now owns master recordings for six of Swift's albums.
