Adding songs I've never heard to shuffle

Y'all, I really enjoy Spotify. I've made a playlist with like 500 songs that I love and listen to them on shuffle while driving.

HOWEVER. After I watched the Bad Bunny halftime show, all these Latin songs, in Spanish, starting playing while I'm listening to my playlist. Nothing against Latin music but I want to hear my curated songs, not some random music.

They don't show up in my playlist and I've turned off shuffle with suggestions. How can I stop these songs from playing?

Thanks
