Naevis makes her debut with Done - Bop or Flop?

So the lyricist is a Iceland singer Klara Elias who was an part of the Europa Song Contest a few years ago

I wonder if they autotuned the vocals so much because of the fact that they wanted it to not sound like her. Kinda similar to what Yamaha did with Vocaloid, using the voice for their voicebanks, using a different name for the voicebanks and giving them their own character. Seems like they used her voice, for naevis but made it sound different enough to not be mixed up with her own music releases.

Edit: English is not her first language, and it seems SM did not give her any of the English speaking producers to help her with English lyrics
