My Question or Issue

 I have playlists that I don't have any problems with, but there is ONE that your algorithm is way off, as it adds inappropriate songs. The playlist is two albums, 22 songs, from the Horizon family singing at the National Quartet Convention. Basically, these are old Christian hymns.  The suggested songs you add are from The chain-smokers, XXXTentacion, Ariana Grande, Bazzi, Calvin Harris & Sam Smith, Sia, Diplo, and Labrinth, Imagine Dragons, Silk City, Billie Eilish, Khalid, Youngblood, Benny Blanco. These choices are WAY off. I was thinking about making another playlist of songs my Mom likes, to use at her funeral (as she gave me a cassette tape of songs for that, and I don't know if a funeral home will have cassette players when she dies.) But I can't have inappropriate songs pop in between hymns of George Beverly Shea. I hope you don't have an antichristian bias, and this is just some mistake.  I don't see any way to just send them a help message. I tried on facebook too, no luck. Thank you.
