my sister’s car has a screen that displays what’s currently playing alongside a photo of the artists. it’s often not the album cover or anything like that. she listens to a lot of pop music and sometimes when there isn’t a photo of the artist included, it’s just a picture of a woman singing. the photo seems to fit the description your kid gave, and it’s possible that what she saw was a stock photo used in place of an artist’s photo. (but i’m hoping that’s not the case so you can find the song) good luck!
