Like take Britney for example. She branched off from Max Martin and started working with The Neptunes, then Bloodshy & Avant, then Danja, then Dr. Luke, then (sadly) will.i.am, and when she did Glory it was with a bunch of people she either never worked with before or she only did a couple songs with previously. If you can go and work with different people and still make it sound good, then that to me is an artist. Taylor just needs to branch out to different producers for something fresh, otherwise it’s going to ruin her artistry imo.
Like imagine if Britney only worked with will.i.am or Danja. It would start to sound really stale and she’d get ripped apart by critics.
