So when you make a playlist, Spotify would create a list of suggested songs on the bottom of your playlist to add it refresh. These options are usually great. I listen to alost of variety of music, but I've noticed that once I add one or two songs that are in Spanish, instead of giving me a list of suggested songs that are similar to my playlist as a whole, I would only get songs that are only in Spanish music. I'm not sure if this was intentional, but this limits my suggested songs options if I choose to add more music to a playlist. Because of this I would only add songs that are in Spanish when I feel my playlist is complete in order to avoid my suggested songs to add to revert to only Spanish songs. I would hope this would get updated and considered in the future.
