"Walmart pulled Justin Bieber and Celine Dion songs from its playlist
back in 2015, but that wasn't because they affected sales. Their employees just got sick of hearing their songs repeatedly each day."
The article you are referencing is from 2017 - I'm sure a lot has changed about the in-store music pilot turned nationwide roll-out:
Target Has Never Played Background Music, Until Now - http://www.goodhousekeeping.com/life/news/a46146/target-background-music/

Target flips on the background music. Will shoppers turn up the volume? - https://www.mprnews.org/story/2017/09/18/target-store-remodel-background-music-spend-more
Thought this was a funny blatant lie: "Target tested music in 2011 at its Minnetonka Ridgedale location to see what shoppers and
employees thought. Both groups gave thumbs up."
I'm SURE the team members asked gave thumbs up, right with corporate standing behind them with big fake smiles on their faces, LOL.
...I also do not ever recall hearing background music playing in any Walmart stores - the stores by me, anyway.
